Preface

Southern Regional Grid has passed another year with consistent growth and development and during the year the maximum and minimum demands have touched as high and low as 23,372 MW and 10,710 MW respectively. Even with such a large variation in the demand, the frequency could be maintained in the normal band for as much as 96.64% of time, which certainly gives a sense of accomplishment and achievement. With the continued augmentation of the generation and transmission network in the grid, the system grew further stronger and safer, contributing towards another disturbance-free year. During the year, the provisions of CERC orders for revised Terms and Conditions of Tariff and the revised STOA Regulations were implemented with all thrust and measures, resulting in easy transfer of power with the neighboring Regions. The 2000 MW HVDC Talcher-Kolar link which has become a life line for the SR grid was used to carry still higher quantum of power from ER to SR and it touched to a value of 1915 MW. Also, to take care of any eventuality of tripping of HVDC Talcher-Kolar link, the Special Protection Scheme (SPS) was also made fully operational by providing a load relief of 1600 MW in the event of bi-pole trip. The ULDC scheme which is the eyes and ears of the grid operators has continued to play an important role in grid operation and control. To further augment the usage of the ULDC system, a number of training programmes were conducted at SRLDC for enhancing the knowledge-base of the engineers of the constituents in the field of SCADA, EMS and other related functions. With the continued co-operation among the Grid Operators, the system voltages could be maintained well within the permissible limits of IEGC range and thereby minimizing the system losses and maximizing the generation availability. With the advancement in the IT field, several software utilities have also been developed in-house by RLDC for functions like shutdown coordination, outage data of transmission and generation elements and data base in respect of STOA transactions. Aiming towards paperless working and to achieve maximum possible transparency, SRLDC has taken steps to post all the scheduling and commercial data on its web site www.srldc.org along with the daily, weekly and monthly system operation reports. This document in the form of ‘Annual Report’ contains the highlights and progress the SR system made during the year as well as the details of power supply position and system parameters. Feed back on the report and/or suggestions for the further improvement is most welcome.

HIGHLIGHTS DURING THE YEAR

1.1 Power Supply Position

During the year 2005-06, the power supply position in the Region has been satisfactory and there was an addition of capacity generation to the tune of 875 MW. In order to have overall economy and efficiency, power was also exchanged with the neighboring Regions on opportunity basis. During the year the energy and peak MW availability in the grid also increased by 4% (daily average energy increased from 406.5 MU per day to 417.4 MU per day and peak MW increased from 22,364 MW to 23,372 MW).

2004-05

During the rainy season of the year, the region has got good inflows compared to last year and during different parts of the year most of the regional constituents have exported the power to neighboring regions through STOA transactions and UI. This year the region has witnessed a maximum consumption of energy 517.5 MU on 24th March 2006 and maximum peak demand of 23,372 MW on 29th March 2006. 1.2 Frequency Regime

During the year for 96.64% of the time, the frequency was within normal band i.e. between 49.0 to 50.5 Hz and the frequency profile was satisfactory. However during certain period of the year, particularly during the months of February-March 2006 the frequency sustained in the low range due to high demand coupled with low generation at some stations due to shortage of fuel etc.

Similarly on the neighbouring 400 KV buses also, there has been improvement of about 3-8kV in the voltage levels. The improvement in the voltage profile has been made possible due to judicious switching in and switching out of the VAR controlling devices (reactors and capacitors etc.), changing of transformer taps as well as participation by the generating units in VAR management. The month wise details of the maximum, minimum and average of daily minimum and maximum voltage of important 400 KV substations are given in Section 9.2

1.4 Short-term Open Access (STOA)

During this year a number of transactions under STOA were approved by SRLDC as nodal agency and simultaneously approval/consent was also accorded for wheeling of the power from ER/NER to WR/NR through SR. During the year 2005-06 , a total 865 number of cases were processed in Southern Region involving intra-region, inter-regional and wheeling transactions under STOA and a total energy quantum of 5604 MU was approved, leading to transfer of substantial power from surplus areas to deficit areas. The energy quantum transacted during the year is 80% more than compared to the last year, which was in the range of 3113 MU from 148 transactions. In view of the higher usage of transmission network due to open access, significant amount of relief to the SR constituents was also possible towards payment of annual transmission charges.

1.5 Inter – Regional Exchanges

Depending on the system conditions on opportunity basis, there has been a remarkably large UI exchange with neighboring regions. In the year 2005-06, SR has exported to WR, the energy to the tune of 403 MU and imported the energy to the tune of 348 MU. The figure shown below indicates the details of UI exported from SR to WR/ER on a typical day where the export under UI was to the extent of 8.57MU and during certain period exported quantity was as high as 718 MW to WR and 585 MW to ER. By exchanging UI with neighboring regions SR has gained to the tune of Rs.80 crores net during the year 2005-06. 2

2.2 FUNCTIONS OF SRLDC As the ‘Apex Body’ for operation of the integrated Grid, the statutory functions of

SRLDC are:

• Optimum scheduling and despatch of electricity within the Region;

• Monitoring grid operation ;

• Keeping accounts of quantity of electricity transmitted through the Regional Grid;

• Exercising supervision and control over the Inter-State Transmission System

(ISTS);

• Responsible for Carrying out real time operations for grid control and despatch of electricity within the region through secure and economic operation of the regional grid in accordance with the Grid Standards and the Grid Code.

2.3 CHANGED FACE OF OPERATION OF SR GRID

• With the commissioning of Gazuwaka HVDC Pole II, power handling capacity increased to 1000MW. This is also helping in evacuation of Talcher – II power in case of any contingency on Talcher-Kolar HVDC link/ER system.

• Power handling capacity of Talcher-Kolar HVDC increased to 2000MW

with the successful commissioning of Special Protection Scheme at Talcher. • By commissioning of 400KV Madurai-Trivendrum D/C lines, inter-

connection between Kerala and Tamil Nadu is strengthened. • By commissioning of 400KV Kaiga-Narendra D/C lines, evacuation of

Kaiga generation made easy. This also helps in reducing the overloading problem of Kaiga-Guttur lines.

2.4 SPECIFIC ACHIEVEMENTS OF SRLDC

2.4.1 Grid Security and Safety

The SR grid security and safety has been enhanced remarkably in the recent

past following taking up of large number of measures as stated above and close coordination with the different Control centers/Utilities. As a testimony to this, it can be seen that no major grid disturbance in Southern Region has taken place in the last couple of years.

2.4.2 Economic and Efficient System Operation In view of the strengthening of the network and various reactive control

measures like switching in/switching out of the Reactors, changing of Transformer Tap positions and operation of generating units in synchronous condenser mode etc.,, the voltage profile in SR grid has been improved consistently. As a result of the improvement in the voltage profile the overall system loss in the region is also being reduced, bringing about overall economy and efficiency.

ABT has infused a sense of commercial awareness amongst all the constituents of the region and has brought about a marked improvement in the system parameters and economy and efficiency in the Region. Open access in Power trading also helped the constituents to make best utilization of available resources which led to economy as well improvement in system parameters.

2.4.3 Metering and Settlement System under ABT Regime

SRLDC plays an important and a key role in metering and settlement system in Southern Regional grid. Over 300 Special Energy Meters (SEMs) of 0.2S accuracy class have been installed and commissioned covering 70 locations in the region in order to measure active as well as reactive energy exchanges at various inter utility exchange points of the States and ISGS. The data from these meters are read on weekly basis on every Monday and transferred electronically to SRLDC for processing and validation and for preparation of weekly Unscheduled Interchange (UI)/Reactive Energy (RE) accounts. SRLDC also operates and maintains Pool Account for UI and Reactive Energy Charges in the region. With the excellent support rendered by Constituents, No outstanding dues remain to be settled in pool accounts.

2.4.4 In-house development of operational utilities In view of transfer of REA responsibility to SRLDC from 1st April 2006,

requisite software utilities have been developed by SRLDC for the energy accounting calculations and successful mock accounts have been prepared for the months of Feb & March 2006.

2.4.5 Training for operators on ULDC scheme In order to enhance the skill of the system operators/development engineers at different control centers in the regions, SRLDC has conducted various training programmes including RTNA, NMS, RTU and XA-21 user level modules using in-house and external faculties. These training programmes have given a lot of confidence to the operators/development engineers, in order to utilise the facility provided under ULDC scheme in best possible manner. Training also provided to engineers on Grid Management & Open Access had helped to gain good knowledge for grid operation.

2.4.6 SRLDC Website:

SRLDC website www.srldc.org has been designed to give the latest and relevant information in regard to grid operation and control. In order to update all the players and other agencies in and outside the grid, the various power supply position (psp) reports prepared at SRLDC on daily, weekly and monthly basis, and other relevant reports/documents are regularly uplinked to the website. The complete range of information related to daily schedules, bilateral contracts, un requisitioned surpluses, real time data, energy meter data and the pool account operation details etc. are also available on the website bringing about complete transparency in the entire process and leading to a zero dispute regime.

2.5 GRID SECURITY ENHANCEMENT USING SPECIAL PROTECTION SCHEME A specially designed protection scheme in order to safeguard the system in

the event of tripping of 2000 MW capacity HVDC Talcher-Kolar link has been designed and implemented in the SR Grid during the year. Under the phase-1 of the scheme which was already operational, automatic load shedding of the order of around 600 – 800MW used to be carried out in the event of tripping of HVDC link by transmitting inter-trip signals to distant sub-stations through PLCC Channels. During the year under phase 2, the scheme has been augmented further and from 28th March 2006 a total load relief of around 1500 MW from sub-stations of all the states is achieved by communicating trip signal through wide band communication network. The scheme has been of immense help in enhancing the SR grid safety and security in the event of tripping of HVDC Talcher-Kolar links.

2.6 THE ROAD AHEAD Indian Power Sector is witnessing major changes. Recognizing that electricity is one of the key drivers for rapid economic growth and poverty alleviation, the nation has set itself the target of providing access to all household by the end of the XI Plan, i.e. around end 2012. Further, the widely distributed and increasing demand of the Regions is required to be met in an optimum manner. Supply of reliable and quality power of specified standards in an efficient manner and at reasonable rates is another challenge ahead for all the Power Engineers. The enactment of Electricity Act 2003, its amendments and changes in Open Access Regulations in ISTS were already brought about in this direction. Revised IEGC 2006 norms help the operators to maintain the grid in safe and operable limits. The another important issue which required to be addressed in right earnest is harnessing large quantum of unutilized generation available with CPPs and IPPs within the States would not only help the grid meet its increased demand but also give assistance on STOA and opportunity basis to neighbouring Regions in crisis situations. Implementation of intra-state ABT in the State is also on the anvil and this would help in rationalization of tariff and scheduling process within the States for the generators and its distribution companies. It is of prime importance that States make all possible efforts to achieve this goal by optimizing their generation as well as by adopting best possible grid side management techniques through good load forecasting methods and other available means.

ULDC SCHEME IN SOUTHERN REGION

4.1 Overview The Unified Load Despatch Scheme (ULDC) in SR was commissioned in January 2002. The scheme envisaged installation and commissioning of Remote Terminal Units (RTUs), integration of existing RTUs in Karnataka, Tamil Nadu and Unit Territory of Pondicherry, installation and commissioning of dedicated communication system comprising of Fibre Optic, Microwave and PLCC system, installation and commissioning of Auxiliary Power supply system such as UPS, DG set, 48V D.C supply system and installation of EPABX system. Under this scheme the Regional System Coordination Centers (RSCC) & Central Project Coordination Centers (CPCC) were established at Bangalore whereas State Load Despatch Centres (SLDCs) were established at Mamidapally (Andhra Pradesh), Bangalore (Karnataka), Kalamassery (Kerala), Chennai (Tamil Nadu) along with system control center (SCC) at Pondicherry. Under each SLDC, Sub-LDCs were also established. The hierarchy of ULDC in Southern Region is given below:

A list of RTUs integrated in ULDC scheme is enclosed as Annexure-I. Also, connectivity details of Workstations, Front-End Processors and Application Servers at RSCC and SLDCs are enclosed at Annexure-II 4.2 Specific Functions The SCADA-EMS system in ULDC is a suite of various Applications covering a broad spectrum of functions like Pre-Dispatch, Real-Time and Post-Dispatch functions. The details of these functions and their deployment in RSCC, SLDC’s and Sub-LDC’s are given in Annexure-III

4.3 Communication Package A strong Communication Backbone is the key to the smooth functioning of the ULDC scheme. The Communication backbone is mainly on Fibre-Optic and Microwave links whereas the last mile connectivity is mostly on Power Line Carrier Communication (PLCC) links. The details of Fibre-Optic and Microwave Communication packages are given below. The Geographical map showing the details of Communication Backbone Network is enclosed at Annexure-IV

As the back up route to different SLDC’s was on the same physical route (through Optical Fibre Cable/Microwave), outage of the physical route was causing loss of data. In order to provide reliability & redundancy in data communication channel, an alternate physical route between SRLDC & SLDC’s has been established through a separate agency (i.e. BSNL) which has greatly improved the data availability/reliability. 4.4 Energy Management System Under this scheme various Energy Management System (EMS) modules have been implemented in the different control centers (RSCC/SLDCs). The power application functions under EMS package implemented in control centers support operational requirement of the SR grid and can be broadly grouped into Pre-dispatch, Real time dispatch and Post-dispatch functions. The Energy Management System (EMS) tools such as state estimation, contingent analysis, optimum power flow, load forecasting, resources scheduling and commitment has provided system operators greater flexibility in taking appropriate and judicious decisions during the course of operation. To supplement further, the following operational tools have been developed 4.4.1 Power Network Analysis (PNA) Module:

Due to complexity associated with the size of Power Network Analysis (PNA) module, the common network model was truncated control area-wise with view to develop different truncated model at the respective state and then to integrate the same to a common network model. All SR states have developed their PNA model separately. The models developed in Andhra Pradesh (AP) and RSCC have already been integrated at RSCC and is working satisfactorily. Similarly, models

13


developed in Kerala (KSEB) & Tamil Nadu (TNEB) have also been integrated at Kerala & the same is also working satisfactorily. This has given an additional tool to system operator to do the contingent analysis more accurately. The integration process of integrated AP+RSCC model & TN +KER model has begun.

4.4.2 Disturbance Data Collection (DDC) Display:

Disturbance data collection (DDC) module has been fully configured to collect all telemetered parameters for a pre-configured interval before and after a disturbance. The ‘disturbance trigger’ can be a single event or a complex set of violation in the grid. During a grid disturbance or system occurrence the snap shot of the entire grid is stored in the system. Generally a pre-disturbance period of 5 minutes and a post disturbance period of 15 minutes information are available. DDC display is run to view the events that have taken place 5 minutes prior and 15 minutes after the disturbance. This tool has helped system operator in analyzing the grid occurrences more accurately to a large extent.

4.4.3 Data Extraction Tool (GET DATA)

A data extraction tool (GET DATA) has been developed which facilitates the system operator to extract data from the Temporal Data Base system and guides them to take appropriate decision during the system operation.

4.5 Monitoring Complexity Under this scheme, more than 30,000 Analog and Status points have been wired up covering more than 300 nodes across the Southern Region and the data from all these nodes are updated every 10-15 seconds. The complexities of the Southern Regional Grid in monitoring and control is as depicted below
