Abstract

Power system losses have turned out to be a major challenge for electricity utilities

worldwide. Bulk of the losses occurs in electricity distribution. In 2012, the overall energy

loss and the distribution system loss in the Sri Lanka power system were about 14% and

10% of the gross generation respectively. Before formulating strategies for loss reduction, it

is essential to determine the losses at each level. Once losses are segregated, utility can

clearly identify their priorities and launch effective programmes to arrest losses.

The objective of this research study is to segregate losses in a selected area of the

distribution system of Ceylon Electricity Board, and evaluate an advanced metering solution

in view of reduction of losses. Western Province North of which the distribution network

spreads in the entire Gampaha district, Sri Lanka, was selected for the study. Accordingly,

the losses were segregated into medium voltage network loss, losses in distribution

transformers and low voltage network loss. The total energy loss in the distribution system

was 7.1% of the energy input to the system in 2012. The loss in the low voltage network

was 5.1 % of the total energy input. However, it was 15.7% of the energy input to the low

voltage network itself.

A study was also carried out to determine losses in the low voltage networks of two

distribution substations. The technical losses were estimated and thereby the non-technical

losses were derived. The total losses were 13.9% and 8.8% of the respective energy input to

the low voltage networks of the two substations. The technical losses were 5.1% and 4.8%

while non-technical losses were 8.9% and 3.9% respectively. The viability of an advanced

metering solution was assessed based on the same low voltage networks. Deployment of

advanced metering systems solely with the purpose of arresting non-technical losses is not

viable. However, viability of full scale deployment of advanced metering shall be studied at

broader level considering any future requirements for time of use metering, avenues for

demand side management, opportunity to reduce system peak through demand response

principles, possible levels of reduction of losses and other benefits to utility and country as a

whole.

Key words – Technical Loss, Non-technical loss, Load factor, Load loss factor, Advanced

CHAPTER 1

INTRODUCTION

1.1 Background

Energy loss in an electric power system is the difference between energy input to the

system and the energy billed on the consumption of consumers connected to that

particular power system. Energy losses or losses in short, are present in any power

system in spite of how carefully it is designed. In other words, losses in electric

power systems are unavoidable. In the present global picture where there is ever

increasing demand for energy, energy losses in any power system raises concerns to

the utility, society as well as the country as a whole where it belongs to. It has

significant economical, financial and societal impacts amidst the continuing global

energy crisis.

Energy losses occur at different levels of the power system, namely in electricity

generation, transmission and distribution. Utilities worldwide are implementing

various strategies and measures to minimize losses in the power systems. It is in fact

a scenario where continual, diverse and time variant efforts and strategies are

essential in order to maintain losses at certain minimum levels and to further reduce.

In the Sri Lanka power system, Ceylon Electricity Board (CEB) owns electricity

generation, entire transmission network and major part of electricity distribution

system. There are independent power producers that generate electricity and supply

to the CEB transmission system, in addition to the CEB’s own generation. Lanka

Electricity Company Pvt. Ltd. (LECO) owns a small part of country’s distribution

network in the coastal areas. There were a total of 5.47 million grid connected

electricity consumers in the country by the end of the year 2012. The total electricity

sales in the same year was 11,691 GWh [1]. The figure 1.1 shows the present

structure of electricity industry in Sri Lanka. Since 2009 with the enactment of new

electricity act, CEB was granted licenses by Public Utilities Commission Sri Lanka

2

(PUCSL) for generation, transmission and distribution of electricity. Four licenses

for electricity distribution were issued to the four distribution divisions of CEB.

Figure 1.1 Structure of Electricity Industry in Sri Lanka [2]

CEB being the country’s largest electricity utility had around 4.97 million

consumers by the end of 2012. The four distribution divisions of CEB serve about

90% of the total electricity consumers in Sri Lanka. The remaining consumers are

served by LECO [1].

Electricity transmission and distribution losses in Sri Lanka were much higher

before the year 2000. However, a significant reduction in the losses is noticed

thereafter [3]. At present the level of transmission and distribution losses in the

country remains around 14% of the gross electricity generation. Transmission and

distribution losses in developed countries are ranging from 4–12% [4]. Table 1.1

3

shows the variation of the gross electricity generation, total power system losses and

transmission and distribution losses in the country from 1990 to 2010. The total

losses include the electricity consumption for the own use of power plants in

addition to the transmission and distribution losses.

2009 9,963.87 16.03 14.37

2010 10,718.27 14.78 13.87

The total energy loss in the Sri Lanka transmission network in 2011 was 4.52% of

the energy purchased by the transmission licensee from the generation plants [5].

Accordingly, the average energy loss in the electricity distribution system in the

country is around 10% of electrical energy purchased from the transmission

licensee. In the circumstances, it is clearly evident that the losses in the country’s

power system are predominant in the electricity distribution system. Therefore, more

attention is required to reduce distribution losses in view of reducing overall losses

in the country’s power system. The distribution losses consist of electrical energy

losses at different levels and different forms in the distribution system. Therefore,

4

segregation of distribution losses is of paramount importance to identify the losses at

each level. It enables the distribution network utility to formulate strategies and take

corrective measures to reduce losses at different levels and in different forms, and

thereby effectively reduce the overall distribution losses.

Advanced Metering Infrastructure (AMI) is a technology which has made its way

into the utility business as a smart solution for metering, monitoring and control of

individual electricity consumers. AMI consists of smart electricity meters,

communication infrastructure, and central data and billing management systems. It

is mostly linked with the modern smart grid concepts and considered to be the initial

building block of smart grids.

AMI replaces the existing conventional electro-mechanical meters or electronic

meters, the manual meter reading process and billing systems. It can be viewed as a

prospective solution for arresting non-technical losses in the distribution network in

addition to a host of other benefits such as implementing time base pricing systems,

remote meter programmability, disconnection and re-connection, outage

management, power quality measurements, avenue for active consumer participation

in energy conservation, etc. AMI and Smart Metering have drawn much attention of

the electricity utilities worldwide, since many of them have already implemented

AMI at least on pilot basis. Therefore, the technical and financial viability of AMI in

the context of distribution loss reduction is discussed in this thesis.

1.2 Distribution Losses

Distribution losses can be segregated into the following components.

Technical losses

Non-technical losses

5

Technical losses are due to actions internal to the power system. Technical losses

consist of dissipation of power in various electrical components of the system such

as distribution lines both medium and low voltage, transformers and measurement

systems. Technical losses can be determined or computed provided that the load

conditions of the system considered is known.

Non-technical losses (NTL) are due to actions taking place external to the power

system or the distribution system. NTL are often unaccounted by utilities due to

unavailability or lack of information. Hence, it is extremely difficult to have an

accurate estimation of NTL in our distribution system. NTL are generally derived

after estimating technical losses. It can be attributed mainly to electricity theft or

pilferage, errors in metering and billing, fraudulent meter reading or billing and

errors in estimating technical losses. It is the general understanding that NTL occur

only in the electricity distribution network.

The table 1.2 shows the performance of the distribution licensees (DLs) in Sri Lanka

for the year 2011. In calculating the energy loss, energy sales values have been

adjusted by PUCSL to accommodate the allowed energy use for street lighting [6].

1.3 Electricity Consumer categories in distribution system

Depending on the energy demand, electricity consumers in the distribution system

are categorized into two.

6

Heavy consumers

Low voltage ordinary consumers

Heavy consumers are those who have contract demand exceeding 42 kVA. They are

charged for the maximum demand in kVA and for the active energy consumption.

There are again two sub-categories of heavy consumers depending on the voltage

level they are metered. There are heavy consumers metered at 33 kV or 11 kV level.

The rest of them are metered at low voltage level. When supplying power to heavy

consumers metered at medium voltage level, energy loss occurs only in the medium

voltage network. However, utility incurs losses in the medium voltage network as

well in the transformers when supplying to heavy consumers metered at low voltage

level. Both CEB and LECO have implemented various measures to arrest technical

and non –technical losses in their respective distribution systems. Heavy consumer

meters have already been converted to advanced electronic meters with remote

meter reading facilities and strict seal management systems have been implemented.

In the circumstances, NTL in the heavy consumer category are at very minimum

level or almost negligible.

Low voltage ordinary consumers are not charged for maximum demand. They are

charged only for the monthly active energy consumption. Utilities incur losses in the

medium voltage network, distribution transformers and low voltage network in

supplying to these consumers, in addition to NTL.

1.4 Existing metering system of low voltage consumers

The individual energy consumption of entire electricity consumer population in the

country is measured through conventional electro-mechanical energy meters. These

meters record cumulative active energy consumption. There is no facility to record

consumption during different time intervals. It is an isolated device lying in the

consumer premises which has no communication facility what so ever. In order to

7

issue the monthly bill, a meter reader of the utility has to visit the premises and take

the meter reading, and issue the bill accordingly.

Noticeable features of the existing low voltage consumer metering system in CEB

are listed below.

All single phase meters are electro-mechanical meters

There are both electro-mechanical and electronic three phase meters

Single register energy recording and no Time Of Use (TOU) energy

recording

Meter accuracy for active energy measurement is class 2

Manually read, no communication between meters and utility

Vulnerable to tampering, no tamper detection facilities

No self diagnosis facilities of meter faults or errors

Poor and irregular practices of meter installations (E.g. Unavailability of

meter enclosures, cut-out fuses or MCBs etc.)

Poor meter sealing practices and lack of proper meter seal management

system

Lack of standardized and regular routine meter testing or replacement

programmes

Presumably, there are heavy losses both in technical and non-technical form in the

low voltage network. It is the general understanding that NTL are present totally if

not predominantly in the low voltage network. AMI appears to be a good solution to

arrest NTL as it is being tried and tested by various utilities. However, it is first

required to assess the level of NTL present in the system before bringing in any

AMI solutions. Adopting AMI systems involves heavy investments on the part of

utility. Mass scale conversion to AMI is a large investment decision even for the

country as a whole since these have to be fully imported spending significant

amounts of foreign exchange.

1.5 Scope of study

Western Province North (WPN) is one of the three provinces in Distribution

Division 2 (DL 2) of CEB. It is geographically located in Gampaha District of

Western Province in the country. In 2012, WPN served around 540,000 electricity

consumers and the total annual electricity sale was 1,755 GWh. It was about 18% of

the total electricity sales of CEB for the same year. The revenue for the same period

in WPN was about 25 million rupees which was 16% of the total revenue of CEB

[1]. Therefore, this province is of high financial significance to CEB. The area is

highly industrialized and has a high population density as well. This study is aimed

at determining energy losses at different levels in the provincial distribution system,

and the technical and financial viability of AMI in the context of arresting NTL in

the province.

1.5.1 Objectives

CHAPTER 2

ELECTRICITY DISTRIBUTION SYSTEM IN SRI LANAKA

2.1 Electricity distribution systems

Electricity generated at the generating stations is conveyed to the end consumers

through transmission and distribution networks. The part of the power system which

distributes electrical energy for local use is termed as the distribution system. It is

the electrical system between the grid substations fed by the transmission network

and the meters of the end consumers.

Depending on the nature of current, electricity distribution systems can be

categorized into AC and DC distribution systems. AC distribution systems are the

most common because; the alternating voltages can be easily changed in magnitude

by using transformers. Distribution systems can also be categorized into two based

on the type of constructions. Those are overhead and underground electricity

distribution systems. However, there are distribution systems where there are both

overhead and underground distribution.

AC distribution systems consist of two main parts; the primary distribution system

and the secondary distribution system. Primary distribution system operates at

voltages higher than the level of general utilization. The voltages used are generally

33 kV, 11 kV, 6.6 kV and 3.3kV. The primary distribution system handles large

amounts of electrical energy compared with the secondary distribution system.

Primary distribution is a 3-phase, 3-wire system due to economic considerations.

Secondary distribution is the part of the AC distribution which operates at voltages

at which the ultimate consumers utilize electrical energy. The voltages are 230 V or

110 V and those are 3-phase, 4-wire systems.

Modern distribution utilities have to operate their systems at stipulated voltage

levels, provide required power demands and maintain high levels of reliability.

11

Whilst doing that, they have to make every effort to minimize all forms of losses in

order to sustain their business in an era of energy crisis.

2.2 Electricity distribution in Sri Lanka

The electricity distribution in Sri Lanka is done by two organizations namely,

Ceylon Electricity Board and Lanka Electricity Company as described under the

section 1.1 in chapter 1. Primary distribution is done mainly at 33 kV level by CEB.

However, in certain areas there is distribution at 11 kV level as well. LECO has its

primary distribution totally at 11 kV level. The configurations of the secondary

distribution systems of both utilities are 400/ 230 V, 3-phase, 4-wire systems. The

transmission licensee of CEB feeds the distribution system of CEB itself at 33 kV

level. LECO is fed at 11 kV level through 33/11 kV primary substations.

In a perspective of distribution loss analysis, it important to look at the components

of the distribution system through which the electrical energy flow occurs. The

electricity distribution systems of the distribution licensees in Sri Lanka consist of

the following major components.

Medium voltage network (11 kV and 33 kV)

Primary substations (33/ 11kV)

Heavy supply consumers metered at 11 kV and 33kV

Distribution transformers supplying to heavy consumers

(11kV/ 400V or 33kV/400V)

Distribution transformers supplying to LV consumers

(11kV/ 400V and 33kV/400V)

Low voltage network

Low voltage consumers

12

The figure 2.1 illustrates the major components and the electrical energy flow in the

electricity distribution system.

Figure 2.1 Energy flow in the distribution system

The DL 1 of CEB covers the largest geographical area in the country. The DL 4 is

the smallest among the four distribution licensees of CEB. However, LECO serves

the smallest geographical area among all the five DLs in the country. The

distribution network architecture and its components are quite similar in the four

DLs in CEB. However, there are certain differences between the distribution

systems of CEB and LECO. The figure 2.2 shows the geographical boundaries and

operational areas of each distribution licensees in the country.

The DL 2 of CEB has the highest number of electricity consumers among all the

DLs which is 28.6% of the total number of electricity consumers in Sri Lanka. The

electricity sales of DLs are also important in comparing the performance of the DLs

in the country. The electricity sales in GWh of each DL for the first half of 2012 are

shown in the table 2.2. DL 2 of CEB had the highest energy sales among all DLs

during the first half of 2012. It was 28.8% of the total electricity sales of all DLs[8].

The energy losses in DL 3 and DL 4 of CEB show noticeable drop in the first half of

2012 compared to 2011. However, the reasons for such variations were not readily

available.

2.3 Technical losses in distribution system

Technical losses are due to actions internal to the power system. Technical losses in

the system are inherently influenced by components and system designs. The current

flowing in an electrical network results in the following types of losses.

Copper loss or I2R loss due to resistance of conductors

Dielectric losses

Radiation and induction losses due to electromagnetic fields generated

surrounding the conductors

Therefore, technical losses are due to dissipation of power in various electrical

components of the system such as distribution lines, transformers and measurement

systems. A list of such components in the local distribution system where power

dissipation occurs is mentioned below.

MV distribution lines

Transformers supplying to low voltage heavy consumers

Distribution transformers

Low voltage distribution lines

Consumer service lines

Voltage regulators

Capacitors

Electrical burdens in metering equipment

All other electrical devices necessary for the operation of the distribution

system

16

The losses in the transformers are twofold: the fixed losses (core loss) and the

variable losses (copper loss). The losses in the power distribution lines including

service lines are due to conductor loss. In electro-mechanical type metering

equipment, power dissipation occurs in the voltage and current elements. In

modern solid state or electronic meters, losses are due to the power dissipation in

various solid state components in the meter boards.

Technical losses in different parts of the distribution system add up to the total

technical loss in the system. The losses present in each part need to be identified and

quantified in the study. It is widely understood that technical losses in a given

distribution system depends on how it is designed and operated. Some common

practices of utilities which may cause to increase losses are listed below.

Lack of attention to minimization of losses in planning and construction of

medium voltage distribution lines

Presence of over loaded distribution lines and associated delays in

augmentation or capacity enhancement of such lines

Availability of equipment with a lower level of energy efficiency, such as

distribution transformers

Loading of distribution and LV consumer transformers at much lesser level

than their rated capacities

Lengthy LV feeders contributing to high level of technical losses

The presence of single phase LV feeders

Unbalanced loading of 3 phase LV feeders

Poor electrical connections at various joints

Further, increased level of harmonics in a distribution system also increases losses.

Technical losses can be accurately computed provided that the load conditions in the

power system are known. Typically, load flow studies or network simulations are

used to calculate technical losses.

17

2.4 Non-technical losses (NTL)

2.4.1 Overview and Sri Lankan scenario

NTL are due to actions taking place external to the power system or the distribution

system. NTL are often unaccounted by utilities due to unavailability or lack of

information. Hence, it is extremely difficult to have an accurate estimation of NTL

in distribution systems. The general practice is to derive NTL after estimating

technical losses.

NTL represent an avoidable financial loss for the utility. It is the amount of energy

not billed but consumed. NTL also reflect a social issue. The consumers who are

accurately metered and billed are subsidizing those who do not pay for the

electricity consumed. In general, NTL in the electricity distribution is high in

countries where Gross Domestic Production (GDP) per capita is low. However,

there are exceptions such as Thailand and Indonesia who have achieved very low

levels of non-technical losses irrespective of lower GDP per capita. It can be mainly

attributed to the social tariffs provided for the poor at affordable prices in such

countries. NTL is reportedly very high in countries such as India, Bangladesh, Latin

American countries. Developed countries such as Australia, UK and South Korea

have very low levels of NTL, as low as 1% total generation. [9].

In the Sri Lankan context, even though there are no accurate estimates for non-

technical losses, it is believed that non-technical losses in CEB distribution network

is around 5% of energy input to distribution. However, this figure may vary

depending on the area of network. In the Northern and Eastern provinces, NTL is

apparently higher than in the other provinces owing to terrorist activities which

prevailed in those areas until recently. The different forms NTL and their causes are

discussed in detail with more emphasis on the experience in CEB’s distribution

system.

18

2.4.2 Electricity theft

Electricity theft can be defined as a conscious attempt by a person to eliminate or

reduce the amount of money that he or she will owe the utility for electrical energy

consumed. It is generally viewed as the major source of NTL by the electricity

utilities worldwide. Two main forms of electricity theft can be identified; namely,

directly connecting an unmetered load to a power line and tampering with the

electricity meter in order to reduce or stop recording the actual energy consumed.

Direct connections to power lines

Direct connections to power lines are much easier and safer in low voltage

electricity distribution systems. It is even easier when the lines are bare conductors.

However, the possibility of direct connections to high or medium voltage lines

cannot be completely ignored. These illegal connections are done by hooking up

wires to bare conductors. Cases have been reported where wires were hooked up

permanently to line conductors. However, the common form is temporarily hooked

up connections which are kept connected intermittently. The illegal direct

connections are mostly detected in rural and shanty areas. Non-frequent inspections

on the part of utility has arisen avenues for direct connections in rural areas.

However, the scenario is apparently different in urban shanty areas where the

general law and order is not properly implemented. Direct connections and other

means of pilferages are higher in those areas.

Unauthorized direct connections are done by hooking up wires to a phase conductor

and the neutral. Sometimes, it is done by just hooking up a single wire to a phase

conductor and making the earth as the current returning path.

Tampering with meter and metering accessories

This is probably the most common form of electricity theft in Sri Lanka. Once the

security seals of the meters are broken, there is ample access to the inside of the

meter housing, and there are a number of ways and means to fix the meter to stop or

19

slow down recording. However, there are cases reported where meters have been

tampered even without breaking meter seals.

There is a noticeable cause behind the abundant meter tampering. The present

technology of electro-mechanical meters used for billing low voltage electricity

consumers is over one hundred years old. The public are familiar with the

technology and working principle of electro-mechanical meters. Due to the presence

of mechanical components inside, these meters are susceptible to physical damages

or shocks.

The figure 2.3 shows three phase and single phase electro-mechanical meters used

by CEB.

Figure 2.3 Single and three phase electro-mechanical meters used by CEB

Figure 2.4 illustrates the elements inside a meter which are most vulnerable to

tampering.

20

Figure 2.4 Parts of a single phase meter where tampering often occurs [10]

The common physical methods of tampering these electro-mechanical meters are

listed below.

Adjusting brake magnet to slow down disc rotation

Inserting various objects to slow down or stop rotation of disc

Stopping the register by inserting various objects

Miss-alignment of disc by shaking the meter

Changing the position of the meter from vertical axis of mounting

Additionally, there are ways of electrically manipulating with the meter to slow

down, stop or reverse its operation.

Interchanging meter input and output electrical connections

Removal of the link of the voltage coil such that voltage coil is not energized

(Only the current coil is energized)

Removing incoming neutral connections and using another neutral to

continue the supply path.

By-passing the meter

21

Listed below are a few methods of tampering with heavy consumer metering

systems where there are current transformer operated meters.

Short circuiting secondary side of current transformers

Reversal of current transformer polarities on the secondary side

Removal of voltage connections to the meters

Removal CT connections to the meters

2.4.3 Other forms of Non-Technical Losses

Whilst electricity theft is considered as the major form of NTL, the other forms of

NTL are,

Defective energy meters

Un-metered connections

Errors and delays in meter reading

Arranging false meter readings by bribing utility staff

Errors in billing

Assessed meter readings

Errors in estimation of technical losses

2.5 Economic impact of losses

Energy losses represent losses in revenues for utilities. To recover costs involved in

the supply of electricity and to fill the utility viability gap, costs of losses should be

covered by paying users or by Governments via targeted output-based subsidies.

Since one or more generators must produce this lost energy and since these

generators expect to be paid for all the energy they produce, a mechanism must be

devised to take losses and their cost into account in electricity markets. A fair

mechanism is one in which participants that contribute more to losses (e.g. remote

generators and consumers) pay a larger share than the others.

22

On the demand side, loss reduction and improvement on energy efficiency would

partially cover the expected demand rise offsetting the need to increase the installed

capacity. On the supply side, the impact on the utility to finance new generation

capacity can be delayed or avoided if reduction in demand can be achieved by

implementing good demand side management measures. The use of energy efficient

compact fluorescent lamps (CFL) in place of conventional incandescent lamps at

large scale for domestic and other lighting applications is a typical example of such

a demand side management measure. The estimation of losses at the levels of

generation, transmission and distribution is essential for vertically integrated utilities

where there is limited transparency into the overall system.

Even when access to the grid is available, customers in many developing countries

are plagued by unreliable power. Where system inefficiencies and theft create

significant losses, utilities are unable to cover their costs. The result is that the

utilities or companies struggle with solvency and are unable to provide high-quality

service to existing customers, let alone deliver new connections.

2.6 Reduction of distribution losses

The amount of energy loss in a distribution system is a key measure of the

performance of the distribution utility. In the present scenario of ever increasing

demand for energy while conventional sources of generation facing a gradual

depletion, reduction of losses in electrical power systems is vital. It benefits the

consumer, utility and country as a whole.

Since losses represent a considerable amount of operating cost, accurate estimation

of electrical losses enables the utility to determine with greater accuracy the

operating costs for maintaining supply to consumers. In order to implement loss

reduction measures effectively, it is essential to segregate the distribution losses with

sufficient accuracy. It is also critical to know if the expected target of technical

losses is indeed technical, whether it is possible for reduction without changing the

23

components and system design. Lower technical losses will provide for cheaper

electricity and lower production costs.

Increased revenue through reduction of NTL is real financial boost for any utility

since the investments involved in implementing NTL reduction programmes are

much less than implementing technical loss reduction programmes. Further, when

the consumers who consume electricity illegally have to pay for their actual

consumption, they will adjust their consumption to match their capacity to pay. This

reduces the energy demand, which will create the same effect as reducing technical

losses. Listed below are some measures to reduce distribution losses and increase

revenue for the utility.

Prevention of theft

The presence of a strong legal framework to punish culprits of electricity

theft is an important factor in arresting NTL. Increased and improved meter

inspection and testing programmes, full refurbishment of meter installations

to prevent unauthorized access (Proper sealing and seal management

systems)

Social contracts with communities for legal connections

Encourage communities to go for legal connections through awareness

programmes. Reduction of initial costs of obtaining electricity connections

and subsidizing for electricity for the poor

Management of payment risk

Special tariff schemes such as TOU tariffs

TOU tariffs can control peak time demands enabling the utility to avoid

costly generation at critical times

Improvement of commercial process

Arresting lapses in billing systems. Enabling web access for consumers to

check their electricity accounts.

Installation of advanced metering systems and pre-paid meters

Encourage consumers in energy saving by providing consumption related

information. Tamper detection and alarming. Operational benefits to utility

24

through remote meter reading, disconnections and re-connections etc. This is

discussed in detail in chapter 6.

There about 1,200 MV and LV bulk consumers in WPN as at end 2012. A

noticeable fact in the distribution system in WPN is that approximately 65% of

electricity sales are for heavy consumers. Only 35% of energy is sold to low voltage

ordinary consumers.

26

2.7.3 Distribution losses in WPN

The electricity distribution losses in WPN as a percentage of energy input to the

system have been at 7.7%, 7.6% and 7.3% in 2010, 2011 and 2012 respectively

[11][12]. The electrical energy flow in the distribution system of WPN occurs as

stated below.

Energy loss in the medium voltage network and primary substation

Energy supplied to heavy consumers with high voltage metering (HV bulk)

Energy loss in transformers of heavy consumers

Therefore, energy losses occur in four areas; medium voltage network, heavy

consumer transformers, distribution transformers and LV network. The segregation

of these losses in the distribution system of WPN is discussed in chapter 4. Table 2.7

presents results of meter testing programme carried out in the province during the

period from 2010 to 2012.

CHAPTER 3

MODELLING AND ESTIMATION OF DISTRIBUTION LOSSES

3.1 Introduction

In order to estimate the technical losses in a selected distribution system, the losses

at different levels of the system need to be estimated. Medium voltage network,

power distribution transformers and low voltage network are three major

components of concern. There are different models and techniques which can be

used for the estimation of losses with acceptable level of accuracy. Some of the

commonly applied models and techniques are discussed in detail in this chapter. The

models and techniques discussed are applied in chapter 4 to estimate technical losses

in the distribution system of WPN, CEB.

3.2 Medium voltage network

Load flow studies are carried out to estimate distribution losses in the medium

voltage network. Mapping the selected network with details in the selected load flow

analysis software such as Synergee or PSS was the initial step in the process. Then

allocation and assignment of loads on to the mapped network was done based on

actual load reading data available. In general, load flow studies are carried out for

the peak loads. As a result, the losses calculated are in the form of peak power losses

of network under consideration. However, it is required to calculate the average

power loss in order to derive the energy loss in the MV network.

The loss of energy in any electricity network varies with time. A hypothetical time

known as ‘Utilization time of losses’ or ‘UTL’ is defined such that losses during

UTL with a continuous load equal to the peak power loss is the same as the loss with

actual loading over the day[12], [13].

An empirical formula known as Jung’s formula is used to calculate UTL [12], [13].

29

Peak demand is the peak electricity demand in the considered MV network. The

average demand is generally obtained by dividing the energy consumed by the

period of time such as one year, one moth or a day.

Alternatively, the method of load loss factor can also be used to calculate the

average energy loss, when the detailed load profile is known. It is discussed in

section 3.3.2.

3.3 Power distribution transformers

3.3.1 Losses in transformers

The losses in power distribution transformers are twofold.

Fixed loss

Power dissipated by the core’s magnetizing inductance. This is a function of

applied voltage and frequency. It is fixed irrespective of the current flow in

the transformer and known as Iron loss.

Variable loss

This is a function of winding current and known as copper loss. It is present

only in the loaded condition of the transformer. Copper loss is proportional

to the square of current flow in the winding.

In the no load condition, if the transformer is energized, only iron loss is present. In

order to calculate total losses in a power distribution transformer, it required to

calculate both iron and copper losses separately. The total technical loss in a

transformer is the addition of iron and copper losses [14].

Transformer manufacturers specify fixed loss and variable loss at the rated current

of the transformer.

3.3.2 Load loss factor and estimation of energy loss

Energy loss of a transformer depends on how it is loaded over a period of time. The

following terms are important in understanding the energy loss of transformers.

The average power loss of a transformer is given by the equation 6,

LCLI lossPower (6)

Where,

LI - Iron loss of the transformer

LC - Copper loss of the transformer (Average)

LI remains constant while transformer is powered. However, the copper loss varies

with the current flow in the transformer. Utilization Factor (UF) of a transformer is

defined as follows.

capacity ratedat Current

demand maximumat Current

capacity Rated

demand Maximum factor ion Utilizat- UF (7)

(4)

31

Copper loss is proportional to the square of the current flow in the transformer.

When the copper loss at the rated full load capacity of the transformer is denoted by

LCR, copper loss at maximum demand (LCm) of the transformer is given by,

LCm = LCR x (UF)2 (8)

Therefore, the average copper loss of a transformer (LC) is given by,

LC = LCm x LLF

Therefore, by multiplying the power loss given by the equation 6, energy loss of the

transformer can be calculated. The relationship between load factor and load loss

factor is explained by the following empirical formula [15], [16].

0.3k0.15 ere wh,LF x k)-(1 LFk x LLF 2 (9)

The value of coefficient k can be assumed or replaced with calibrated factor if

metered data is available. Generally k=0.2 is used by utilities to calculate losses of

distribution transformers [13], [15], [16].

3.3.3 Calculating energy loss of a large number of transformers

When a particular area of an electricity distribution network is considered, there are

a large number of power distribution transformers. Instead of calculating the losses

of individual transformers, a statistical method can be applied to approximately

calculate the total loss of all the transformers under consideration. However, the

following details of the transformers are required for the calculation.

Capacity rating of each transformer

Peak loading of each transformer

Fixed and variable losses of the transformers for each rating

The table 3.1 is used to approximately determine the total losses of the transformers

When LF is known, LLF can be calculated using value k=0.2 which is generally

accepted. Then, average power loss of a transformer can be calculated using the

formula (6) stated in the section 3.1.1. Then the total power loss of all the

transformers of a given rating is calculated by multiplying average power loss of a

transformer by the number of transformers. The calculations are repeated for each

available rating of the distribution transformers.

3.4 Low voltage distribution network

3.4.1 Overview of low voltage network

Unlike feeders in a medium voltage network, feeders in a low voltage network are

fairly short and do not vary in length over a wide range. But it is the low voltage

33

network that penetrates into almost every corner of urban, semi-urban or rural areas

where there is electricity. LV feeders consist of un-transposed three phase, two

phase or single phase line segments. These supply electricity to balanced or

unbalanced three phase loads, two phase loads and single phase loads. As a result,

almost all LV feeders have unbalanced voltages and currents and non-zero neutral

currents.

In the circumstances, in order to analyze these conditions, it will be required to

model all three phases of LV feeders accurately. However, in the general practice,

some approximate methods of modeling are applied for the analysis. All such

approximate methods of modeling assume perfectly balanced three phase systems.

The loads are assumed to be balanced three phase and all the line segments are three

phase and perfectly transposed. Under these assumptions, single phase equivalent

circuit for the feeder can be used.

A single phase line to neutral equivalent circuit of a three phase low voltage feeder

supplying a balanced three phase load is shown in the figure 3.1.

Figure 3.1 Single phase equivalent circuit [17]

The figure 3.2 shows the phasor diagram representing the above equation.

Voltage drop across the reactance is leading the current phasor by 90 degrees

Dashed lines represent the real and imaginary parts of the impedance (IZ)

The voltage drop down the line is defined as the difference between the magnitudes

of the source and load voltages.

When the angle between the source and load voltages (δ) is very small, the voltage

drop between the source and load is approximately equal to,

3.4.2 Uniformly distributed loads

When loads are uniformly distributed along a feeder it is not necessary to model

each load to determine voltage drop or power loss in the feeder. The figure 3.3

shows a generalized line with n uniformly distributed loads.

Where R = r. l, the equation 19 gives the total three phase power loss for a discrete

However, the model in figure 3.6 does not provide the correct results for the voltage

drop of a uniformly distributed feeder. In order to have correct results for the voltage

drop as well as power loss, the exact lumped load model shown in figure 3.7 can be

used.

CHAPTER 4

ESTIMATION OF DISTRIBUTION LOSSES IN WPN

4.1 Introduction

Estimation of provincial electricity distribution losses was done based on the data

available in the planning division of the province for the year 2012. The focus in this

chapter is to estimate the losses in the medium voltage network and the distribution

transformers.

The losses in the distribution transformers were estimated under two categories,

namely, the low voltage heavy consumer transformers and distribution transformers.

The distribution transformers supply electricity to the low voltage consumers

including street lamps. Figure 4.1 illustrates the major components in the provincial

distribution system and the way energy flows from grid substations up to low

voltage consumers.

4.2 Medium voltage network

The details of the medium voltage network of the province are shown in the table

4.1.

Weasel lines : 230.65km UG Cables : 3 km

Copper : 26.15 km

Total : 1608.23 km Total : 126.01 km

Based on the Medium Voltage Development Studies Region 2, 2012 – 2021[11], the

provincial energy and power demand for 2012 are as follows.

The total annual energy demand = 2,314 GWh

Peak power demand = 456 MW

Peak power loss = 8.32 MW

Therefore, average load factor (LF) = 2,314,000/ (456 x 24 x365)

= 0.579

Using Jung’s formula,

Utilization time of losses (UTL) = x0.57921

8760579.020.579 22

= 3,171.91 hrs per year

Therefore,

Energy loss per year = 8.32 x 3,171.91/ 1000

= 26.39 GWh

41

Percentage energy loss = 26.39/ 2,314 x 100%

= 1.14%

Therefore, the average energy loss in the medium voltage network in Western

Province North as a percentage of total energy input to the province is 1.14.

4.3 Transformers of low voltage bulk consumers

The details of bulk consumer transformers in terms of number of transformers and

their capacities are summarized in the table 4.2. The details are based on the

information available in the provincial planning unit as at the end of year 2012.

According to the manufacturer’s specifications (Lanka transformers limited) the full

load and no load losses of each transformer rating is shown in table 4.3.

The monthly energy consumption and the maximum demand of each bulk consumer

are available in the billing system of CEB. The table 4.4 illustrates how the LF, LLF

42

and UF are calculated for 2 low voltage heavy consumers. The data in the first four

columns were obtained from the CEB billing system. There were a total of 1,043 LV

heavy consumer transformers in WPN for the month of January 2012. Therefore,

there would be 1,043 records in the table.

The table 4.5 illustrates how the rest of the calculations were done to find the

average power loss of each heavy consumer transformer. The values of no load and

full load losses of the transformers were obtained from the table 4.3. The average

power loss of each transformer is calculated using formulae explained under the

section 3.3.1 and 3.3.2. The relevant energy loss based on the calculated power loss

for the January 2012 is shown in the last column of the table.

The calculations were repeated for all available bulk consumer transformers in the

province for each month in 2012. Table 4.6 shows the results of calculations of

43

monthly total energy loss of the LV heavy consumer transformers and the total

energy loss of the same for 2012. Accordingly, the total annual energy loss in the

low voltage bulk consumer transformers is around 9.5 GWh.

From the provincial energy sales data, the total energy sales to LV bulk consumers

for the year 2012 was 485 GWh. Therefore, the energy loss as percentage of total

annual energy input to the transformers was estimated to be 1.92.

4.4 Distribution transformers (Supplying low voltage consumers and street

lamps)

The details of electricity distribution transformers in terms of number of

transformers and their capacities are summarized in the table 4.7. Based on the

annual peak time load readings taken by the provincial planning branch, distribution

transformers were grouped into five ranges of loading. Accordingly, the number of

transformers, falling into each range of loading against their rated capacities is also

shown in the table 4.7.

To calculate the losses, transformers belonging to a particular capacity are first

selected. Then the average loading of the selected transformers are calculated. The

results of the calculation for 100 kVA distribution transformers are shown in the

table 4.8.

80 – 100 77 90 6,930

Total (∑f) 341 ∑(X/2) f 18,450

Average loading of a 100 kVA transformer = ∑(X/2).f / ∑f

= 18,450 / 341

= 54.1 kVA (54.1% of rated capacity)

According to table 4.3, the no load and full load losses of a 100 kVA transformer is

340 W and 1,900 W respectively. The average system load factor of national grid in

2012 is used for the calculations [18].

45

Therefore, taking LF = 0.57,

LLF = 0.2 x 0.57 + 0.8 x 0.572 = 0.37

Average power loss of a transformer = No load loss + UF2

x LLF x (Full load loss)

= 340 + 0.5412x0.37x1,900

= 546 W

Therefore,

Power loss of 100 kVA transformers= 546 x 341

= 186 kW

Similar calculations are done for the other available ratings of distribution

transformers. The results of the calculation are shown in the table 4.9.

Table 4.9 Total power loss of the distribution transformers

Rating in kVA 630 400 250 160 100

Power loss per transformer in W 1,929 1,368 847 614 546

Total power loss in kW 35 109 268 536 186

Therefore, the total power loss of all the transformers = 1,134 kW

Annual energy loss of the transformers = 1,134 x 24 x 365

= 9.9 GWh

4.5 Overall energy flow in the distribution network in WPN

The table 4.10 summarizes the energy flow in the provincial distribution system up

to the low voltage network level.

Table 4.10 Summary of annual energy flow in the distribution system, WPN

Total annual energy input to WPN 2,314 100.0

Energy supplied to LECO 417 18.0

Energy supplied (sales) to HV bulk consumers 619 26.8

Medium voltage network loss 26 1.1

Energy supplied (sales) to LV bulk consumers 485 21.0

Energy loss in LV bulk consumer transformers 10 0.4

Energy loss in distribution transformers 10 0.4

Therefore, energy input to LV network 747 32.3

Energy loss in distribution network in WPN = (Energy purchased) – (Energy sales)

= 2,314 – (417+619+485+606)

= 187 GWh

Energy loss as a percentage of energy input = 187/ 2,314 x 100

= 8.1 %

According to the decision on electricity tariffs effective from 01st January 2011 by

PUCSL, allowance of energy for street lighting for DL 2 is 1.37% of its energy sales

[19]. The same basis is used to estimate the consumption of street lamps in WPN.

The total energy sales of WPN except the sales to LECO in 2012 are taken for the

calculation.

Estimated energy consumption of street lamps = 1,710 x 1.37/100

= 23.4 GWh

Energy loss without street lamps = 187 – 23.4 = 163.6 GWh

Percentage energy loss without street lamps = 163.6/ 2,314 x100

= 7.1 %

47

Aggregate of losses of medium voltage network and all transformers

= 26 + 10 + 10 = 46 GWh (2.0 %)

Therefore, energy loss in the low voltage network only of WPN is calculated as

follows.

Energy loss in low voltage network without = 163.6 -46 = 117.6 GWh

Consumption of street lamps (X)

Therefore, energy loss in the low voltage network as percentage of total energy input

to WPN,

X as percentage of total energy input to WPN = 117.6 / 2,314 x 100 = 5.1 %

Further, it is important to know the energy how much of energy input to the low

voltage network is lost.

X as a percentage of energy input to LV = 117.6 / 747 x 100

Network

= 15.7 %

Energy loss in the LV system includes both technical and non-technical losses. Even

though LV network loss in the overall provincial energy scenario is less, it is much

higher in terms of energy input to the LV network. The technical losses consist of

LV network conductor loss, losses at service drops, losses at various joints of the

conductors, service wires and terminations and energy consumption of electricity

meters. In order to further segregate the losses in the LV network, the power

consumption of electricity meters can be estimated.

The power consumption of a typical single phase electro-mechanical meter used in

CEB is around 1 W [20].

Number of ordinary consumers in WPN = 541,700 [11]

48

Assuming each consumer is installed and measured through a single phase electro-

mechanical meter,

Total power consumption of meters = 541,700 W

Therefore, annual energy consumption = 4.7 GWh

Therefore, the energy loss excluding the power consumption of electricity meters, as

percentage of total energy input to the low voltage network,

= (117.6 – 4.7)/ 747 x 100

= 15.1%

49

CHAPTER 5

SAMPLE STUDY – LOW VOLTAGE NETWORK LOSSES

5.1 Introduction

Low voltage network supplies electricity to ordinary consumers. The ordinary

consumers include those supplied under the domestic, religious, small scale

industrial and general purpose tariff categories. The street lighting is also in the low

voltage network. The share of ordinary consumer electricity sales is about 56 % total

electricity sales in the country. It indicates that 56 % of the total electrical energy

utilized in the country is channeled through the low voltage distribution system. The

table 6.1 shows the comparison of electrical energy consumption of the ordinary

consumers and the low voltage distribution line lengths in the entire country and the

provincial LV network of Western Province North, CEB for the year 2011 and 2012.

Table 5.1 Details of electricity sales and LV line lengths [1], [11], [12], [21]

Total low voltage line length in km 108,886 112,995 8,121 8,329

The share of ordinary consumer energy sales in WPN is much less than the same in

the entire country. It is mainly due to the existence of a large number of industries

including a number of major industrial processing zones in WPN. In the chapter 4, it

was derived that the energy loss in the LV network of WPN is 15.7 % (118 GWh in

2012) of the energy input to the LV network. It is a relatively higher level. However,

the true gravity of the losses in LV network is generally not reflected since the

overall distribution loss in WPN is about 7.1%.

50

The objective of this chapter is to further segregate the losses in the LV network

based on a selected area of LV network in the province. The sample study is aimed

at determining technical and non-technical losses present.

5.2 Selection of substations and low voltage network for sample study

Two substations and the low voltage networks fed by those two substations were

selected for the sample study. The details of the substations are in the table 5.2. The

substations had multiple feeders with three phase and single phase feeder segments.

The substation is identified in the utility context by its unique Substation

Identification Number (SIN).

There were seven LV feeders from the two substations selected. All the feeders were

bare All Aluminum Conductors (AAC, 7/3.40mm). The total three phase and single

phase line lengths were 10.8 km and 2.6 km respectively. There were a total of

1,135 consumers in the two substations.

51

5.3 Methodology

In order to find the electrical energy loss in the LV network selected, the

methodology adopted is explained below.

Installation of outdoor type current transformers and energy meters near the

substation at the beginning of each feeder. The initial active energy reading

of each meter was noted.

Meter readings of all consumers on each LV feeder were obtained. Meter

readings were taken during period the supply is interrupted for installation of

current transformers and meters with support of meter readers.

A survey was carried out to obtain details of street lamps connected to each

feeder. The type and the power consumption (Wattage) of each lamp and

number of lamps available were noted.

The distance of each feeder and spur lines connected were measured.

The individual service connections and consumer meters on each feeder were

inspected and tested to detect the presence of unauthorized usage, defects

and faults of meters and their accuracies.

After a certain period of time (one month), consumer meter readings on each

feeder were obtained. The readings were taken within a short span of time

such as one hour. The feeder meter readings were noted just before starting

to obtain individual consumer meter readings and just after finishing

individual consumer meter readings. The mid value of the two readings was

taken for calculations.

The load profile data including apparent and active power flows, variation of

current and power factor averaged over 15 minute time spans were

downloaded from the digital meters installed at the feeders. The profiles

covered the whole period of measurement.

The photographs in the figures 5.1-1 and 5.1-2 show how the outdoor type current

transformers and the meters were installed for measurement at the substation H 048,

Veyangoda.

5.4 Calculation of distribution system losses

Initially, the total distribution loss of each feeder was calculated. It included both the

technical and non-technical components. Then the technical loss (I2R loss) of each

LV feeder was estimated. The non-technical loss of each feeder was derived by

subtracting the technical loss from the total loss of each feeder.

5.4.1 Calculation of distribution losses (Technical + Non-technical)

The active energy consumption recorded at each LV feeder meter was calculated by

subtracting the final cumulative energy reading from the initial reading. The same

procedure was followed to calculate the energy consumption recorded on the

individual electricity meters of the consumers on each feeder.

Electricity consumption of the street lamps was estimated assuming 12 hrs of

burning per day. The results of the calculations are shown in the table 5.3.

The meters of the individual consumers were electro-mechanical and of accuracy

class 2. The electronic or programmable poly-phase meters installed at the feeders

were of accuracy class 1. The outdoor type current transformers used to provide

secondary current output to the feeder meters were of accuracy class 1.

54

5.4.2 Calculation of technical losses

The technical losses were estimated based on four models. The models used are,

Uniform load distribution

Full load lumped at mid-point of the feeder

One half load lumped at the end of the feeder

Exact lumped load model

The details of the above models with the relevant formulae for the power loss were

explained in the chapter 3. The average peak load on each feeder during the period

of measurement was obtained from the relevant load profiles downloaded from the

feeder meters. The average peak current per phase of each feeder was also

calculated. The lengths of the main section of each feeder (Without spur lines) were

used for the power loss calculation for the last three models mentioned above. The

table 5.4 shows the results.

Under the uniform load distribution model, a load flow analysis was done for each

feeder to determine the peak power loss. The software programme “SynerGEE

Electric 3.5” was used for the analysis.

55

Uniform load distribution models were constructed for the load flow study. The

peak power loss of each feeder was calculated by the load flow studies.

The figure 5.3 shows the layout of LV feeders of the Gampaha, G011 substation on

the SynerGEE platform. The feeders were constructed and shown separately for the

purpose of clarity.

The peak power loss as a percentage of the input peak power demand is indicated in

the last column.

A similar analysis was done for the 3 feeders in the other substation. The figure 5.5

shows the layout diagram of feeders in the Veyangoda, H 048 substation on the

SynerGEE platform.

The figure 5.6 shows a screen shot of the load flow analysis results. The peak power

loss as a percentage of input peak power demand is indicated in the last column.

In order to determine the energy loss over the period of measurement, it was

required to calculate the average power loss of each feeder. For this, the average

57

load factors and thereby the loss load factors of the feeders were calculated. The

table 5.5 elaborates the calculation of LF and LLF of the feeders.

The equation 7 explained under the section 3.1.1 was used for the subsequent

calculation of the load loss factor. The calculation of the LLF for the feeder 1 of the

G011 substation is shown.

LLF = 0.2 x 0.543 + 0.8 x (0.543)

2 = 0.344

Finally, the energy loss of each feeder under the four models was calculated. The

equation below was used for the calculation of energy loss once the peak power loss

of each feeder had been calculated.

Energy loss = Peak power loss x LLF x period of measurement in hours

The results of the calculations are shown in the table 5.6. Out of the four models, the

models where the loads were lumped at mid point and half load lumped at the end

point show the highest and the lowest values of the energy losses respectively. A, B,

C and D indicate the four models, Uniform load distribution, Full load lumped at

mid-point, Half load lumped at end point and exact lumped load model respectively.

Considering the two substations separately, the technical loss of the LV network of

the substation G 011, Gampaha varies from 3.3% to 6.6%. The same for the H048,

Veyangoda substation varies from 2.6% to 5.2%.

5.4.3 Derivation of Non-technical losses

The non-technical component of energy loss is derived by subtracting the technical

component from the total energy loss. The non-technical loss of each feeder in

terms of energy in kWh and as a percentage of total energy input to the feeder is

shown in the table 5.7. The results of the technical losses based on the uniform load

distribution model have been used for the calculations.

As discussed in the chapter 4, the NTL component tabulated above include any

errors in the estimation of technical losses, energy loss at service drops and joints,

losses in the electricity measuring instruments etc. However, the losses in the

electricity meters can be estimated in order to further consolidate on the levels of

NTL. Assuming that the power loss of a single phase active energy meter is 1W

[20].

Power loss of meters in G 011 substation = (Number of meters) x 1 W

= 770 x 1 W

= 0.77 kW

Energy loss for 27 days = 499 kWh

Energy loss as percentage of energy input = (499/ 82,355) x 100 %

= 0.6%

Similarly, for the substation in Veyangoda,

Energy loss in 375 consumer meters = (365 x 1 x 24 x 21/1000) kWh

= 184 kWh

60

Energy loss as percentage of energy input = 184/22,690 x 100 %

= 0.8 %

Therefore, the NTL as a percentage of energy input excluding the power

consumptions of the meters are 8.3% and 3.1% for Gampaha and Veyangoda

substations respectively.

CHAPTER 6

ADVANCED METERING TECHNOLOGY FOR LV

CONSUMERS

6.1 Advanced metering technology – overview

Advanced metering technology or advanced metering infrastructure is a fully

configured combination of systems which is integrated into existing applications and

processes in the power system. It provides an intelligent connection between the

consumer and the utility operator. AMI generally include the following sub-systems.

Smart meters or advanced meters

Communication system between smart meters and utility central stations

(Wide area network)

Home area network

Meter data management system

Operational gateways

Smart meters are solid state programmable devices. In comparison to conventional

electro-mechanical meters which only record the cumulative energy consumption,

smart meters have a host of other features. In general, they can have some or all of

the following features [22].

Implementing time base pricing (TOU – Time Of Use, CPP-Critical Peak

Pricing or dynamic pricing tariffs)

Remote meter programmability

Provides consumption data to customer and utility

Net metering

Pre-payment metering

Remote meter disconnection and re-connection

Direct load controlling or load limiting for demand response purposes

62

Outage detection and reporting

Power quality monitoring

Detection of tampers or energy theft

Facility for integration into home area network to communicate with other

devices

CEB already implement Automated Meter Reading (AMR) system for its bulk

supply customers. AMR is an initial step in reduction of manual meter reading costs

and eliminating reading errors or frauds to improve meter reading accuracy. In some

cases utilities globally have migrated from AMR to AMI, or in the case of domestic

or retail customers sectors, directly from conventional metering infrastructure to

AMI. AMI or smart metering system is the initial step of realization of concepts of

modern grids. To envisage, two-way communication between the customer and

utility, motivation and inclusion of the customer to actively participate in demand

side management activities. Figure 7.1 illustrates the architecture of a fully fledged

AMI solution [23].

Figure 6.1 Architecture of an AMI solution

63

DER and MDMS stand for Distributed Energy Resources and Meter Data

Management Systems. Utilities and experts worldwide view AMI as a very good

solution for minimizing NTL. In this context AMI offers following advantages.

Requirement of manual meter reading is eliminated; therefore, errors and

frauds associated are also minimized if not eliminated.

All tampers at meter level can be detected easily, therefore, meter level

tampers will also be minimized

Meter disconnections and re-connections are done remotely; therefore, cost

of utilizing staff for this purpose is eliminated

6.2 Comparison with existing metering and billing system of CEB

The figure 6.2 illustrates the existing metering and billing system of CEB. It is

essential to analyze how an AMI solution would merge with or replace existing

activities in metering and billing operations.

Figure 6.2 Existing metering and billing system of CEB

6.3 Cost benefit analysis of AMI

The actual benefits of AMI are diverse. Financial viability of AMI is more or less

subjective. Evaluating viability of AMI considering all these areas where benefits

are anticipated is practically difficult. Diverse input parameters will be required for

64

the evaluation. Such parameters will have to be assumed and used or use results of

previously available research work. Unfortunately, lack of previous research work

and studies in the Sri Lankan context poses a problem.

In the circumstances, the benefits of AMI in the areas explained under the section

6.1 and with emphasis of minimizing NTL are evaluated. The sample of consumers

selected for the analysis of LV network losses in chapter 5 was considered for the

study and evaluation.

Total number of consumers in the sample = 1,135

Assuming all consumers of the selected two LV networks to be single phase,

Number of advanced meters required = 1,135

Cost of a meter mentioned below is inclusive of the provision of the communication

system and central data management systems. The cost was obtained from the bid

price of a reputed supplier quoted to supply an AMI solution similar in configuration

to the architecture in figure 6.1 for single phase consumer meters.

Investment and operational costs

Average cost of an advanced meter in LKR = 8,500

Total cost of investment for meters in LKR = 8,500 x 1,135

= 9,647,500

Assuming GPRS or GSM communication for each meter,

Communication cost per meter per month in LKR = 50

Total cost per year for communication in LKR = 681,000

Based on the standard construction costs of CEB, the cost labour and transport of

replacement of a single phase meter was taken as LKR 2,000 for the calculation.

65

Total cost of labour and transport for new advanced meter installation in LKR,

= 1,135 x 2,000

= 2,270,000

Total investment of the project in LKR = 9,647,500+2,270,000

(Cost of meters and installation) = 11,917,500

Benefits and avoided costs

It is assumed that 100% reduction in NTL since illicit tapping before the meter is

more or less negligible in the sample considered. With deployment of AMI, energy

loss due to NTL will be accurately billed. Therefore, there will be an increase in

revenue for the utility.

Referring to section Substation G 011, and excluding the energy consumption of

meters (Power consumption is taken as 1W per meter)

NTL in for 27 days = 6,794 kWh

Calculated energy loss per year = 6,794 x 365/ 27

= 91,845 kWh

Referring to section Substation H 048, and excluding the energy consumption of

meters (Power consumption is taken as 1W per meter)

NTL in for 21 days = 715 kWh

Calculated energy loss per year = 715 x 365/ 21

= 12,427 kWh

Total energy loss due to NTL = 91,845+12,427

= 104,272 kWh

Assuming average power consumption of an advanced meter to be 2W including the

power consumption of associated communication equipment, the additional power

consumption of an advanced meter is 1W than in the case of analog meters.

66

Energy consumption of advanced meters per year = 1,135 x 1 x 365/1000

= 414 kWh

Energy loss due to NTL excluding energy consumption of meters,

= 103,858 kWh

Average selling price of electricity in 2012 in CEB = 15.56 [1]

Therefore, increase of revenue due to NTL reduction,

Total revenue increase per year in LKR = 113,248 x 15.56

= 1,762,139

Estimated cost of a disconnection in CEB is LKR 800. According to provincial

billing system data for 2012, the total number of disconnections and re-connections

and total number of consumers in the year 2012 in WPN was 24,072 and 541,000

respectively. Accordingly, the number disconnections and re-connections for the

selected sample of 1,135 consumers are calculated on proportionate basis.

Average number of discon./ re-conn. per year = 24,702 x 1,135/ 541,000

= 51 Nos.

Cost of discon./ re-conn. per year in LKR = 51 x 800

= 40,800

Since AMI replaces the manual meter reading, the cost of the same is avoided.

However, the cost of communication is applicable. According to the WPN billing

information, and based on my calculations, the average cost per manual meter

reading is LKR 26. Since the cost of communication per meter is taken as LKR 50,

there will be an additional cost of LKR 24 per reading.

Additional recurrent cost per year for meter reading = 1,135 x 12 x 24

= 326,880 LKR

67

Therefore, Total cost saving per year in LKR = 1,762,139+40,800-326,880

= 1,476,059

Therefore, Simple payback period of AMI deployment,

= 11,917,500/1,476,059

= 8.1 years.

Simple payback period of 8.1 years is not a favourable situation for any commercial

investment. Since the lifetime of a meter is about 10 years, the net savings or returns

are experienced only after 8.1 years or only for 1.9 years. It is about LKR 2.8

milliion which is only 23% of the total initial investment over the entire lifecycle of

the project. Therefore, in 10 years, utility has to make the same investment for the

meters and costs of meter installations. In the circumstances, deployment of an

advanced metering system solely for the purpose of arresting non-technical losses is

not financially viable.

The sample of LV consumer meters selected for the study is not a statistically

representative sample of the total population of consumers in the province.

Therefore, viability of a mass scale conversion or deployment of AMI requires to

be discussed based on data of a more representative sample at provincial level or

country level.

There are technical and social issues which need to be further addressed. The

equipment shall be reliable enough to perform satisfactorily in the local

environmental as well as power system conditions for minimum of ten years. Since

communication technologies are fast developing and transforming, it is necessary to

assure that the support for the present GSM/ GPRS technology is provided for the

next 10 – 15 years by the communication service providers. There is a risk due to

the fact that communication technologies evolve fast. There are other technologies

such as Power Line Communication (PLC) or Radio Frequency (RF) network

68

technologies which are used with advanced meters. The technical and financial

parameters associated with such systems need to be separately studied.

Alternatively, NTL in the selected sample can be reduced if not eliminated by better

management of the existing metering system. The existing induction type single

phase watt-hour meters in general have a life time of over 25 years. The replacement

of defective meters in the system by the same type meters, refurbishment of

metering installation in such way to minimize unauthorized access, strengthening

inspections during monthly meter reading, implementation of meter seal

management systems, regular meter testing and inspections and raids etc. are a

combination of activities which can effectively arrest NTL in a local context. Such

activities are already being carried out by the utility, and what remains is

streamlining of such activities with specific targets. The financial investment of such

work is much less compared to deployment of AMI. Advanced metering systems are

not locally developed, but have to be imported fully. Therefore, the second system

of NTL reduction is not only financially beneficial, but it also saves large amount of

foreign exchange whilst retaining and enhancing the local inputs to the process.

69

CHAPTER 7

CONCLUSIONS, REMARKS AND DISCUSSION

Losses in electrical power systems have become a serious problem to utilities

worldwide. Amidst the global crisis for energy where the costs are ever increasing,

the attention of utilities has shifted towards reduction of losses. The economic,

financial and social consequences of power system losses are being gradually

understood. As such, utilities and countries as a whole are devising various measures

to arrest losses in electrical power systems. However, an initial and essential step

towards reduction of losses is accurately estimating losses.

Losses in electricity distribution represent dominant part in the overall power system

losses. In the Sri Lankan context, losses in the distribution system are around 10% of

gross electricity generation when the total losses in generation, transmission and

distribution amount to 14% in 2012. Though this can be viewed as a reasonably

good level, when compared with the power system losses in rest of the developing

countries in the region, country need long strides to reach the levels achieved by the

developed countries.

In our efforts to arrest losses, it is of paramount importance that the losses are

estimated accurately. It is a pre-requisite before developing strategies to counter

losses. Since distribution losses have the major share in power system losses,

accurately estimating distribution losses is a key to proceed. Distribution loss itself

has components which have been discussed in detail in this thesis. Therefore, it is

required to segregate distribution losses to identify the losses at different levels. The

thesis was aimed at segregating distribution losses in the distribution system of

Western Province North of the Distribution Licensee 2 of CEB. WPN is a key area

in the distribution system of CEB which generate 16% of its revenue. There are 12

such provinces in the distribution system of CEB.

70

The distribution losses at different levels namely, medium voltage network,

distribution transformers and low voltage networks were separately estimated. The

total energy loss as a percentage of energy input to the province was 7.1%. The

medium voltage network loss was 1.14% of energy input. The losses in the power

distribution transformers were at 0.8%. The low voltage network loss as percentage

of energy input to the province was 5.1%. However, the same as a percentage of

energy input to the low voltage network was 15.7%. This implies that losses in the

low voltage network are considerably high, even though its true gravity is not

reflected in the overall picture. The situation was subjected to further analysis

segregating low voltage network loss into technical and non-technical components.

This was done in a selected area of the network, since it was practically difficult to

handle the entire network.

The sample study showed an interesting picture which was an eye opener for the

utility. Total energy loss in the two substations selected were 13.9% and 8.8%

respectively. Technical losses were calculated to be 5.1% and 4.8% respectively.

Non-technical losses accounted to 8.9% and 3.9% of the energy input to the two

substation networks selected. Interestingly, the consumption of street lamps was

estimated to be 4.8% and 1.8% respectively. Since all consumer meters in the

selected networks were tested, test results are interpreted with a view of

understanding the contribution of metering problems to non-technical losses.

Following important conclusions can be drawn with regard to the sample study.

Street lamp consumptions can be very high as they not metered or billed

properly. It is high need of time to device suitable methods to meter

consumption of street lamps

Presence of defective meters contributes significantly to NTL. Well

organized regular meter testing and replacement programmes are essential to

overcome the problem

71

Utility must adopt proper seal management systems, refurbish meter

installation fully without correcting only the meter, to prevent or minimize

avenues for unauthorized access

Proper sealing and installation practices should be used right at the time new

connections are given to prevent addition of new cases which might

contribute to NTL

Setting up standards for regular meter testing programmes at utility or

regulator level

It is required to device programmes such analysing consumer consumption

patterns to identify power pilferages

It is recommended to have broader surveys to determine low voltage network losses

such that entire network can be modeled with sufficient accuracy. It will enable the

utility to implement loss reduction measures very effectively.

With regard to advanced metering technology, it is not viable to replace existing

meters for the purpose of arresting non-technical losses only, but with clear

objectives for reaping other benefits of advanced metering such as a platform

interactive consumer participation for energy conservation, implementation of time

of use tariffs to curtail system peak demand, power quality, interruption and failure

management etc. The relatively short lifetime of advanced meters which is around

10 years, will be a decisive factor when full scale deployment of AMI is considered.

It will be a huge cost to the utility and country as a whole to replace about 5.5

million meters every 10 years. The time taken for such a replacement programme

will be in years. Smart meters will have to be replaced about 3 times to cover a

single lifetime of existing electro-mechanical meters. In the circumstances, it is

strongly recommended to have pilot programmes, since evaluation of AMI

deployment on a broader basis, not confining to non-technical loss reduction

requires a lot of inputs. Lack of locally done studies in this regard is a problem for a

proper evaluation.
