Application Manual – Planning of a High-rise Building

Answers for industry.

Totally Integrated Power

Introduction

The demands placed on a modern high-rise building are constantly

increasing. A high level of safety, flexibility throughout the entire

life cycle, a low level of environmental pollution, the integration of

renewable energies and low costs are common demands nowadays

that already have to be taken into consideration during the planning

of a high-rise building. A special challenge is the coordination of the

individual installations. The main installations are, for example, heat-

ing, ventilation, air conditioning and refrigeration, fire protection,

protection against burglary, building control system and power distri-

bution. In modern planning, the demands on a high-rise building are

not simply split up among the individual installations, but have to be

coordinated. An optimum solution is created from the networking of

the individual requirements. This manual provides an overview of the

most important installations in a high-rise building and describes the

planning of the power distribution as an example.

zones, entire floors and the complete building, even across groups of distributed buildings and campuses.

Buildings are responsible for around 40% of the world’s power consumption. With Directive 2002/91/EC, Energy Performance of Buildings Directive, EPBD, the European Union is trying to improve the energy efficiency of proper-ties. Amongst the most important measures specified are the creation of an energy certificate for buildings (or energy ‘passport’) and the determination of minimum requirements for buildings.

The components of the building automation systems are evaluated with regard to their effect on the energy con-sumption of buildings with the new standard EN 15232, “Energy Performance of Buildings – Effects of the Building Automation and the Building Management”.

In accordance with the new standard, building automation systems (BAS) are divided into four different performance classes (Fig. 1-1).

Class D corresponds to BAS systems that are not energy-efficient; buildings with such systems have to be modernized, new buildings may not be equipped with these systems.

Class C corresponds to the average BAS system requirements currently in use.

Class B designates BAS systems that have been developed further, with better functionality than ‘standard’.

Class A applies to highly efficient BAS systems.

The greatest potential for the optimization of a project is during the planning phase. At this stage, the course is set for additional costs and cost increases which may incur during the erection and subsequent use of the building. Compared to conventional planning, integrated planning continually improves the cost-benefit ratio. When tackling complex tasks, integrated planning takes the synergies of coordinated, intelligent, integrated systems and products from a single supplier into account and implements them in cost-effective solutions. Interfacing and elaborate har-monization of different systems and products becomes obsolete.

1.1 Total Building Solutions

Total Building Solutions establish a balance between the requirements for safety and security of people and prop-erty and the desire for ease-of-use and problem-free oper-ation. The result is a highly automated, intelligent build-ing, designed for the entire life cycle of the property. In its requirements and structures, the Total Building Solution refers to the Technical Building Management (TBM) disci-plines.

These customized solutions comprise:

A central building control system

Security and personnel control systems

Control of heating, ventilation, air conditioning and refrigeration

Automated room and zone controls

Power distribution

Fire protection

Protection against burglary and intrusion

Access control

Surveillance systems (CCTV and video)

Lighting systems

Integration of third-party systems

Display of alarms and building data

1.2 Building Automation

Building automation means the comprehensive solutions and services required in the open-loop and closed-loop control of the heating, ventilation, air conditioning, light-ing and blinds as well as the integration of the power distribution to selected building services elements. Build-ing automation can be applied to individual rooms and

This new standard also contains procedures for the calcula-tion of energy performance by means of user profiles for various complex building types:

Offices, hotels

Classrooms

Auditoriums

Restaurants

Retail centers

Hospitals

Combinations of these standard elements provide clear specifications of how to achieve a certain performance class.

1.3 Fire Protection

Fire requires an initial ignition and then oxygen to keep burning. Therefore, wherever people live and work, there is always a danger of fire. Constructional measures alone are not sufficient to prevent the initial ignition turning into a real fire. For this reason, effective fire protection is essential. Effective fire protection is in place when the following two conditions are satisfied. Firstly, the fire must be detected quickly and clearly and signaled. And secondly, the correct measures must be implemented as quickly as possible. This is the only way to avoid direct fire and conse-quential damage or at least to keep this to a minimum.

Optimally coordinated fire detection, alarm, evacuation and fire extinguishing systems are more effective than separate solutions. The fire protection system can also be easily integrated with a management system in a larger security concept with intrusion protection, access control and video surveillance. This results in the creation of a comprehensive hazard management. Integration in the building control system and the associated intelligent interaction result in a more effective protection of people, property and the environment.

The fire detection system

Intelligent, high-speed evaluation models of advanced fire detection systems such as the SINTESO detectors with ASA (advanced signal analysis) technology enable smoke and fire to be detected immediately and clearly, no matter how difficult the environmental conditions. These detectors can be programmed optimally for the conditions at the loca-tion of use.

The alarm and evacuation system

The effectiveness of clear and unequivocal communication during a crisis situation is also of prime importance in the fire protection. An electro-acoustical or speech-controlled alarm and evacuation system has proven to be the best solution in all cases. Unique fire alarm signals, reassuring behavior rules and clear instructions help to avoid panic breaking out.

The fire extinguishing system

Each application requires a suitable extinguisher. Whether powder, wet, foam or a combination of these extinguishing systems: a fire extinguishing strategy that has been worked out individually and tailor-made not only protects your building, but also the environment when a fire breaks out.

1.4 Alarm and Evacuation Systems

The right information at the right time, at the right place! The ideal equipment for this is an electro-acoustical emer-gency alarm system with speech commands. It enables quick, sensible responses thus providing optimum safety. Rapid evacuation saves lives.

In addition to the prompt detection of the fire, quick and orderly evacuation of the building is of prime importance to save lives. Especially with regard to the changed court rulings on compensation claims, the evacuation is playing an increasingly important role. In tall buildings such as hotels, banks or administration buildings, or in buildings with a large number of visitors such as shopping centers, universities and cinemas, efficient evacuation is of prime importance. The following general rule applies: the faster the evacuation, the greater the chance of survival. How-ever, it is most important that panic does not break out amongst the users or residents of the building. This is best achieved with reassuring information and clear instruc-tions.

It is therefore best when a fire alarm occurs that spoken messages are used for the evacuation. Spoken instructions via loudspeakers are clear, they are understood and fol-lowed. This greatly increases the chances for people to save themselves. For this reason, speech-controlled alarm systems are an ideal complement to fire alarm systems in all buildings.

1.5 Fire Extinguishing Systems

Time as a safety factor: An important element in fire prevention is the time between fire detection and interven-tion. The shorter this time that be kept, the less the imme-diate damage and the consequential damage.

Intervention at an early stage: A fire extinguishing system cannot prevent a fire starting. However, with prompt detection, it can extinguish a fire when it is still small. Especially in buildings where there are special risks (expensive property, high downtime costs, etc.), this is of invaluable, existential importance.

The basis for this is quick and clear detection so that fire sources are detected and located immediately. Depending on the situation, the correct intervention is started at the right time.


Successful extinguishing of the fire: As an automatic fire extinguishing system represents the optimum initial inter-vention method in most cases, Siemens supplies a coordi-nated range of extinguishing systems. Adapted to the respective field of application (risk and target of protec-tion), each of these systems provides optimum protection. The comprehensive range of extinguishing equipment also ensures that the quickest and best effect is achieved, suited to the situation in each special case (Fig. 1-2).

1.6 Planned Security

There is a great potential for risk – terrorism and extrem-ism, environmental catastrophes, fire, robbery, burglary and spying, theft and vandalism. These risks have to be identified and analyzed and the appropriate security con-cepts have to be developed (Fig. 1-3).

Prevention, intervention and rescue measures can be implemented for many of these risks within the framework of the legal standards and guidelines. The aim is to make the future more secure through defined risk management. This means investment for companies, but also benefits: transparency, confidence of members of staff and business partners, improvement in the company image, increase of the credit ranking and clarity about the risk situation.

1.7 Robbery and Burglar Alarm Systems

The necessity to protect people, property and other values against violence and theft was never as great as at present. The subject of security is increasingly becoming an impor-tant economic factor. Therefore, reasonable provisions for the protection of people, the safeguarding of property or irreplaceable objects of value are especially important. Modern risk management takes account of these points.

Four security aspects

Naivety and carelessness help burglars just as much as inadequate security measures. Therefore, protection must be both passive and active: passive through mechanical protection equipment and active with an electronic alarm system. The additional observance of simple security rules and the necessary everyday prudence are another signifi-cant contribution to minimize the risk. Optimum protection of people and buildings is based on the following four pillars:

1. Prudence as free-of-charge protection2. Mechanical protection equipment as the first line of

defense3. Electronic robbery and burglar alarm systems for the

reliable detection of dangers4. Forwarding of alarms for the immediate notification of

personnel providing assistance

Fig. 1-3: Risk management


1.7.1 Electronic Robbery and Burglar Alarm Systems

The crucial question is: is an alarm system decisive for risk management? The following factors must be taken into consideration when answering this question:

Origin of the risks: are these only external risks, e.g. through intruders, or do they also occur within the building, e.g. through employees or visitors?

Objects of value on the property (cash, jewelry and works of art, high-quality production goods and systems, sensitive data, etc.)?

The location of the object to be protected: busy or quiet area?

Risk of vandalism: what does the social environment look like?

Danger of extremism: is there a danger of specific acts of sabotage?

The consequences of burglaries, such as operational down-times, the loss of customer data and the possible resulting damage, must also be taken into consideration. The deci-sive benefit of an alarm system is the protection against the established risks and the minimization or total preven-tion of injury to people or damage to property. This is only possible with the aid of an active security system that immediately sets off an alarm in an emergency situation and also notifies the offices providing assistance.

An electronic system has decisive advantages compared to purely mechanical protection measures. For example, it already detects the first attempt at a break-in and immedi-ately notifies the required security staff. This is not the case with purely mechanical building protection. If not detected, a burglar could make any number of attempts to overcome the mechanical protection measures. If you also consider that mechanical protection measures often can-not be used with modern building components, such as glass doors or special lightweight construction elements, then an active security system is frequently the only alter-native.

We recommend a sensible mixture of mechanical and electronic protection. The more time it takes to break in, the more time the notified security team has to intervene. The burglar also has much less time in the building, which can significantly reduce the possible damage.

1.7.2 Video Surveillance Systems

In sophisticated security concepts, the video system pro-vides the visual basis for decisions and plays a central role – in addition to the real-time monitoring of critical areas – in the identification of persons with the aid of biometric processes, and in the detection of dangers.

Mobile video systems

Whether for the monitoring of external installations, live coordination of service personnel or the management of

•

mobile business activities, the high-speed availability of data and images is a task performed by mobile multimedia monitoring systems. Numerous detectors and cameras are grouped around a mobile digital system that can store multimedia information and quickly pass this on via mod-ern communication networks.

Stationary digital room surveillance

Stationary systems are used for specific room surveillance using the existing IT infrastructures. These systems detect changes and monitor various alarm zones. If an alarm is triggered, the video sequences are recorded digitally and forwarded to higher-level management systems.

Recording of alarm situations

Video surveillance not only detects incidents, but docu-ments the entire process when an incident occurs – from the recording of the video images, the transmission and storage of this information, the initiation of automatic measures through to the centralized data evaluation and archiving.

Video control centers

The communication between the video system and the control center is performed using TCP/IP via any Ethernet, ATM or TN network structure. In conjunction with a Video Web Client, operation, control and access is possible from anywhere in the world.

1.7.3 Time Management and Access Control Systems

Last not least, the future of a company is also a question of the security technology and therefore, the right technol-ogy for access control. The aim is to qualify access authori-zation and at the same time flexibly adapt the authentica-tion of persons to the individual corporate requirements, as well as to be able to individually configure access rights both geographically and chronologically.

The above requirements can only be resolved with the aid of modern systems for access control. Therefore, open system solutions with flexible networks are required. They are only configured under consideration of the intended use of the building and the organization involved. Its special structures and the specific workflows also have an effect. Factors such as the size of the company, the num-ber of people, doors, elevator and access gate control as well as additional functions also have to be taken into account.

Future-oriented solutions include not only the linking of business management applications, but also the integra-tion of other security systems. When linked to the building management systems, the information can also be opti-mally used under energy performance aspects.


1.8 Automated Room Control

Modern automated room control concepts provide inte-grated solutions for the air conditioning, lighting and blinds control as an important precondition for the well-being and performance capability of those using the room. Switches and regulators in various designs, which satisfy individual requirements and architectural demands, are available for the operation of all room functions.

Communicative systems should be used that satisfy the requirements of EN 15232 for a Class A building. Open communication protocols such as LON or KNX/EIB in accor-dance with EN 50090 satisfy this requirement. A further advantage of such systems is the ease they can be ex-tended with or flexibly adapted for various types of use.

1.9 Power Management

High supply and operational reliability and flexible use are the key factors of every modern power distribution. With the energy costs making up a greater share of the total operating costs of the building, optimization of the operat-ing costs through an ecological and economically efficient optimization of the energy and energy costs is an abso-lutely essential goal, which already has to be taken into consideration during the planning.

Only when all the components of the power distribution system have been optimally matched, is it possible to

guarantee a reliable and profitable power distribution, which is beneficial throughout the entire life cycle of the building. A power management system has the following objectives:

Continuous monitoring:

Automatic, time-related recording, monitoring and archiving of status and measurement data, power consumers

Increase in the transparency through visualization of the power flow/consumption within the building, from the point of supply to the final load circuit

Analysis of the energy values:

Analyses of the energy data/flow and provision for further processes

Identification of potential for improvement and savings for the purpose of energy cost optimization

Correct allocation of the energy consumption quanti-ties and costs according to utilization and consumer

Technical and organizational measures:

Optimization and reduction of the energy consumption and costs

Support for purposeful diagnostics and maintenance

In order to sustain the energy performance of a building permanently at a high level, accompanying services are required during the operational phase in order to con-tinuously adapt automation strategies to the changes in use.

Power management system

The power management system is based on the opera-tional level in a building, focusing on power supply and includes the functional layers:

Acquisition for status analysis and measurements

Processing level for the data acquisition (Fig. 1-4)

Operator control and monitoring with visualization, archiving, reports, control of switchgear, status monitoring / measuring points

In order to command of optimum purchase/consumption quantities records during the utilization phase, the required measuring points and the power distribution components to be monitored must be planned and configured at an early stage. Specific room assignments and the fact that this can change must be taken into account.

The following outlines some of the reasons for the imple-mentation of a power management system:

Quick and simple online overview of the states of the power flow/consumption in the building

Validity check of the recorded values, avoidance of reading errors

Optimization of the purchasing contracts adjusted to the individual consumption shares

More precise specification and more economical power consumption through exact knowledge of the demand profile

Transparency of costs in the energy sector

Benchmarking

1.10 Power Distribution

Nowadays the investment costs are of prime importance when planning power supply systems. But the operating and energy costs should not be neglected either, as they can have a sustained effect on the overall cost balance over the period of utilization.

The electrical planning engineers therefore have the respon-sibility of designing power supply systems with operational reliability and energy performance in mind. Their service ren-dered must correspond to the generally accepted rules of good practice. This means that various implementing regula-tions, administrative regulations, relevant standards (IEC, EN, DIN), general legal building test certificates and the general legal building approvals must be taken into account during the planning phase, not only for a specific installation but across all installations involved.

Support for these increasingly complex tasks during planning is provided by solution approaches such as Totally Integrated Power (TIP), which facilitates the plan-ning tasks with integrated solutions and efficient engi-neering tools.

Standards and regulations

When planning and erecting buildings, many standards, regulations and guidelines must be observed and complied with in addition to the explicit specifications made by the building and plant operator (e.g. factory regulations) and the responsible power distribution network operator. These standards and regulations vary from country to country and depend on the location of the building.

Power demand

With regard to the power supply, the most important task is the estimation of the required power. In order to attain a high level of efficiency, the components should work with a utilization of 70–80% of the maximum power: undersiz-ing causes malfunctions, while oversizing results in excess costs.

Network structure and supply sources

The network structure is determined by the requirements resulting from the building’s use. In line with the specifica-tions made by the installation company and the intended use of the building, the required power must be distributed between different sources of supply. If redundancy is a system requirement, an additional reserve must be consid-ered in the planning.

Besides the demand to be met by the general power supply (GPS), the power quantity required from a safe and reliable source of supply must also be estimated. This power de-mand is divided between the redundant power supply (RPS) and the uninterruptible power supply (UPS). The redundant power supply (RPS) is also operated via the second system input from the UPS as a standby system when the general power supply has failed. In addition, the power requirements of safety equipment (DIN VDE 0100-710, DIN VDE 0100-718) to be supplied by the safety power supply system (SPS) must be considered. The di-mensioning of the individual components results from the estimate of the power quantities required and their alloca-tion to different sources of supply.

Electric utilities rooms

Besides the correct dimensioning of the components, another essential planning aspect is the specification of the size and location of the utilities rooms required for the power supply. The dimensions of these utilities rooms depend on the dimensions of the components required and the relevant safety regulations.

Boundary conditions such as room ventilation, ceiling loads and access ways for moving items must also be taken into consideration when drawing up room and building plans. Over-dimensioned rooms reduce the economic efficiency of a building (room utilization). Under-dimen-sioned rooms may hinder the implementation of a certain technical solution or, at least force the use of expensive custom solutions for the technology applied.

Planning of the Power Distribution – Design Example

Chapter 2


2 Planning of the Power Distribution – Design Example

The dimensioning software SIMARIS design provides assis-tance for the dimensioning process. The result of the dimensioning process is the specification of the switching and protective devices as a function of the individual connection distances. When all the components of the power distribution system have been planned, this plan-ning must be incorporated in the tender specification.

2.1 Specifi cations (Excerpt from the Project Description)

For a high-rise office building with shopping arcade in Berlin, Germany, the power supply has to be planned for a 10-story building (12 floors) with a floor area of approx. 25 m x 60 m.

There is a car park for customers in front of the building, the access way to the parking garage (levels -1 to -3 for employees) and a fountain (80 m x 20 m). (Fig. 2-1)

Real floor area approx. 1350 m2 (14 levels + technical equipment on roof level).

Floor heights of levels 00 to +10: 4 m, levels -1 to -3: 3 m

The valid rules and regulations have to be observed.

2.1.1 General Specifi cations

The level of building installations, equipment and furnish-ing should represent an average standard of innovation and comfort.

Emphasis should be placed on energy savings. Single-room control and presence signaling should be provided.

A fire alarm system, video surveillance of the traffic routes, the parking garage, the shopping arcade and the outside area as well as an access control system have to be planned.

The building has external shutters.

The media supply is via two utilities hubs that contain the elevators, staircases, electrical distribution boards, ventila-tion and other media.

Within the levels, the supply routing is in the ceiling.

The power distribution in a high-rise office building is considered in this chapter from the first planning steps to the creation of the specifications of work and services. The required planning steps are shown and explained using an example.

The specifications of the owner/developer with regard to the use of the building must be implemented when plan-ning the power distribution. The supply concept is created taking into account the rules and regulations valid for the building location. The main components are then dimen-sioned. Depending on the supply concept, the consump-tion for the general power supply (GPS), the safety power supply (SPS) and the uninterruptible power supply (UPS) must be determined separately. The expected separate consumptions must be weighted with the associated simultaneity factor (SF) and added up.

The technical data of the components results from the determined energy consumption. The architect can derive important information for the required space and access ways from the technical data and the requirements set by the owner/developer. In addition to the component dimen-sions, pressure relief and ventilation are also important for the correct dimensioning of the rooms.

The power distribution system is then dimensioned in the next planning step. Dimensioning is the rating of all the equipment and components that are to be used within the electrical network. Protection against overload, short-circuit and electric shock as well as the static/dynamic voltage drop and the static/dynamic selectivity are taken into consideration.

2.2 Power Demand Estimate

Approach: based on W/m2, according to the Application Manual, Basic Data and Preliminary Planning, Chapter 3 Determination and Division of Power Demand.

Parking garage / utilities areas (incl. roof area)

Basement levels -1 to -3 with 1,350 m2 each + utilities areas ca. 210 m2 (areas between utilities hubs), assumed average power demand: 10 W/m2

Calculation: (3 x 1,350 m2 + 210 m2) x 10 W/m2 = 42,600 W

Shopping center / bank

Ground level 00 with 1,350 m2, assumed average power demand: 60 W/m2

Calculation: 1 x 1,350 m2 x 60 W/m2 = 81,000 W

Offices

Levels +1 to +10 with 1,350 m2 each, assumed average power demand: 50 W/m2


Refrigeration / ventilation

11 levels with 1,350 m2 each, assumed average power demand: 60 W/m2.


Total power demand

approx. sum: 1,690 kW

Required transformer output

The established total power demand determines the re-quired transformer output. The determination is based on a cos phi = 0.85 and a transformer load level of 70%.

Calculation: 1,690 kW / (0.7 x 0.85) = 2,840 kVA

2.3 Schematic Power Supply Concept

The following aspects should be taken into consideration when designing electric power distribution systems:

Operational simplification due to clear and straightforward network configuration

Low cost for power losses, e.g. by medium-voltage network-side power transmission to the load centers

High reliability of supply and a high degree of operational safety for the plant even in the event of faulted items of equipment (standby power, selectivity, i.e. fault-discriminating system protection, and high availability)

Easy adjustment to changing load and operating conditions

•

•

•

•

Low operating costs thanks to maintenance-friendly equipment

Sufficient power transmission capacity of equipment both under normal and fault operating conditions

Good power supply quality, i.e. low voltage fluctuations owing to load fluctuations at a sufficient level of voltage symmetry and low harmonic content in the voltage

Compliance with applicable standards and project-related rules for special installations

Please also refer to the Application Manual, Basic Data and Preliminary Planning, Chapter 4 Power Distribution Plan-ning in Commercial, Institutional and Industrial Buildings, high-rise building type 3.

2.5.2 Standby Power Supply

The standby power supply consists of the safety power supply system (SPS) and the uninterruptible power supply system (UPS).

Generator for safety power supply

To provide for necessary life safety equipment, such as emergency lighting, elevators for firefighters, etc., a diesel generator as standby power supply unit (t ≤ 15 s) is installed in a container on the rooftop; selected rating 800 kVA.

Manufacturer: MTU

See Application Manual, Basic Data and Preliminary Plan-ning, Section 5.7 Standby Power Supply.

Uninterruptible power supply

The requirements of the system integration in accordance with Totally Integrated Power must be satisfied by an (input-side) frequency- and voltage-independent load supply through double-transformer UPS devices (so-called online devices with double-conversion operation). In this context, the distributed use of plug-in devices can be excluded from the planning.

A CE marking in accordance with Directive 73/23/EEC for low-voltage systems and 89/336/EEC for electromagnetic compatibility is required for the operation of UPS devices within the European Community. These regulations have been included in the international standards for safety requirements (IEC 62040-1-1 for operation in easily acces-sible rooms and IEC 62040-1-2 for operation in locked service rooms) as well as in the EMC requirements (IEC 62040-2).

The UPS is installed at level 5 with a rating of 100 kVA (central arrangement in the vicinity of the main consumer (IT). IEC 62040-3 has been considered for rating the UPS. A central, static UPS system with a separate batteries room was chosen; selected rating 100 kVA.

Model: static UPS, consisting of a rectifier/inverter unit and battery

Manufacturer: Masterguard

See Application Manual, Basic Data and Preliminary Plan-ning, Section 5.6 Uninterruptible Power Supply.

2.5.3 Further Components and Installations

Automated room control

A building management system is included in the planning to provide integrated room control functions (constant light control, presence signaling, shading, room climate control …).

Manufacturer/type: Siemens / instabus KNX/EIB

For details on the integrated room control functions of Siemens instabus KNX/EIB, please refer to the Application Manual, Draft Planning, Section 10.2 Building Manage-ment System.

Note:

Excerpt from the tender specification:

The following contract items are to be delivered and per-formed as a fully operative KNX/EIB building management system.

All power and control cords required for installation, in-cluding their necessary wiring systems, must be included in the respective tender sections.

The supplier should specify and verify the following by proof:

1. ETS3 license number: ...........................................

2. Reference systems (a minimum of two in the same size as the planned installation):System 1: …………………………….............................System 2: …………………………….............................

3. Proof of certification of the company or staff member from an authorized KNX/EIB training center.

Alternatively, a KNX/EIB service provider may be named. Appropriate proof of certification must also be included.

The following basic requirements are placed on the bus:

1. Sound communication according to KNX/EIB standard (EN 50090 and following DIN VDE 0829), twisted wires with a wire diameter of 0.8 mm.

2. Safe isolation from the power network.

3. Bus cables whose wires have a joint enclosure. As a minimum requirement, the bus cables must be rated for the same test voltage between conductor and cable surface, that also applies to power cables.

Bus cable labeled: YCY 2 x 2 x 0.8 mm², normal design, HCH 2 x 2 x 0.8 mm², halogen-free design. First wire pair for signal transmission and power supply, second wire pair as reserve.

If conventional switch and pushbutton inserts are used, it must be ensured that the rockers can be snapped into the frame as a unit.

To ease installation work for positioning the switch, and in order to compensate for wall clearances, the rockers must be furnished with elongated guide pins and the installation devices with flexible contact lever guides.

The calculation of unit prices must include delivery, instal-lation ready for service, addressing, parameterization, testing and switching works, machine-operated labeling, share of documentation, including handing over of project parameterization on CD-ROM, all additional services, small parts and fixtures, terminals and wiring shares, data bus-bars, bus terminals, and scaffolding up to 3 m.

Safety lighting

A safety lighting system consists of the following compo-nents: safety power source, distributors, monitoring de-vices, cabling, luminaires and rescue signs.

Model: CEAG

See Application Manual, Draft Planning, Section 10.4 Safety Lighting Systems.

Note:

Emergency lighting control can be performed by using KNX/EIB and DALI. In this context it is important that the controllers and bus systems for the electrical safety instal-lations be independent of the controllers and bus systems of the building management system. For this purpose, electronic control gear (ECG) with a DALI interface is used in the safety luminaires.

Elevators

Elevators must be chosen with an appropriate load capac-ity for the conveyance of people.

Model: OTIS

See Application Manual, Draft Planning, Section 9.3 Eleva-tor Systems.


The type of connection to ground of the medium-voltage or low-voltage power system should be selected carefully, as it is crucial for the extent of protective measures to be taken. At the low-voltage side, it also determines the system’s electromagnetic compatibility.

Selected power supply system: TN-S system

See Application Manual, Draft Planning, Section 2.1.2 Power Supply Systems according to the Type of Connection to Ground.


Power systems in which electromagnetic interference plays an important part should preferably be configured as TN-S systems immediately downstream of the point of supply. Later, it will mean a comparatively high expense to turn ex-isting TN-C or TN-C/S systems into EMC-compatible sys-tems. The state of the art for TN systems is an EMC-suited design as TN-S system.

2.6 Power System Considerations

2.6.1 Power Supply Systems according to the Type of Connection to Ground


2.6.2 Selectivity in Low-Voltage Systems

Proof of selectivity is required in IEC 60364-7-710 / DIN VDE 100-710 and DIN VDE 0100-718.

See Application Manual, Draft Planning, Section 2.5 Selec-tivity in Low-Voltage Systems.

According to IEC 60947-2, Appendix A, and VDE 660-101, the determination or verification of the desired type of selectivity is divided in two time ranges.

Time range ≥ 100 ms:

The time range above 100 ms can be analyzed by a com-parison of characteristic curves in the L- or S-range. Toler-ances, required protective settings, curve representation in identical scales etc. are to be observed.

Time range < 100 ms:

The standard requires selectivity in this time range to be verified by testing. Due to the fact that the time and cost expense involved is very high, when different devices are used in the power distribution system, selectivity limits can often be obtained from renowned equipment manufactur-

ers only. This is why in practice, let-through currents are often compared to the operating or pick-up currents or, the let-through currents of the protective devices are com-pared to each other.

The prerequisite being that the relevant data is available from the equipment manufacturer and that it is analyzed thoroughly.

In this project, the selectivity was calculated with the aid of the TÜV-certified SIMARIS design dimensioning soft-ware. Components were selected and dimensioned using SIMARIS design.

Note:

A network calculation should always be performed prior to any performance description, forming a basis thereof. Any problems resulting from a wrong device selection/combi-nation/arrangement will thus be detected at an early stage.

Furthermore, a network calculation provides a record of planning reliability with regard to cable cross sections, voltage drop, observance of conditions for disconnection from supply, and the grading distances of protective de-vices.

Power management

1 item Power management systemThe above described power supply system must be equipped with a power management system. The leading product is Siemens.

Measurements/transmission from the switchgear rooms / panels:

In each of the switchgear rooms or in process, measured values and status will be collected via communication-capable circuit-breakers, multi-functional measuring instru-ments or distributed I/Os and transmitted to a programma-ble logic controller (SIMATIC S7) via PROFIBUS-DP or direct interfacing. This controller must be designed with the capacity to generate mean values of measurements, per-form message acquisitions, and store measured values and messages temporarily. If communication to the operator control and monitoring level has broken down, energy data are buffered, so that they can be transmitted when the connection is reestablished.

Central control room – visualization on a PC:

The server shall be installed in a central room. The server communicates with all PLC units (SIMATIC S7) in the switchgear rooms via an OWG ring circuit, it serves for display of all information rendered from the switchgear rooms, for measured value, message and load manage-ment parameterization as well as for data archiving. Client applications on distributed workstations access this server. In a control center the current status of power distribution is displayed. Besides electricity, other energy types, such as gas, compressed air, district heating etc., may also be integrated. Energy quantities, limit violations, individual measured values and switch positions are displayed inform of graphics. Electrical switches can be remote-controlled directly from the operator interface. All switching opera-tions, whether initiated from the control center or directly on site, as well as limit violations of measured values are recorded with date and time and archived. This informa-tion is either visualized as text message or graphically as


switching cycle diagram. Measured value acquisition is performed continuously and compressed and archived as mean values in adjustable increments of 1 to 60 minutes. Values are displayed graphically as load curves. All archived data are available for analysis, export and reporting. A cost management function is available as to map the cost center structure, energy types, consumption values, costs and billing rates. Power distribution is visualized by means of hierarchically structured process images. A plant over-view functions as start screen to access the individual plant component images. Messages and faults/malfunctions can be displayed in the respective component images or in a specific diagnostic image. In addition, there are curve diagrams and tables/statistics.

2.8 Performance Specifi cation of Power Distribution (Excerpt)

The following specification of work and services describes the power supply from the medium-voltage level (rated voltage 10 kV) to the final circuit.

A medium-voltage switchgear plant is to be erected ac-cording to the supply conditions imposed by the responsi-ble power distribution network operator.

In order to build a fully selective power system, specifica-tions made by the network operator in terms of grading times must be observed.

Medium voltage is fed into the system by means of ring-main cables.

The switchgear for medium-voltage transfer is to be deliv-ered as a 6-panel, gas-insulated (SF6) station (ring, ring, metering, CB load transfer, 2 x CB transformer outgoing feeder). It must be possible to extend the station by one feeder panel without redesigning work being involved and within a time frame of a few hours.

The medium-voltage substation consists of 3 panels (feed-in via disconnectors, 2 x CB transformer outgoing feeder)

The transformers are to be designed as low-loss cast-resin transformers with a performance enhancement option by using tangential fans (50%).

The LVMD system, the busbars and the system of trans-former/busbar/LVMD is to be implemented as a type-tested assembly (TTA).

All feeder and coupling switches are to be delivered as air circuit-breakers(ACB) in identical current ratings with guide frame and LSIN releases. The rated current of the release block must be adapted to requirements by means of a rating plug (without replacing the measuring transducer set).

Feeders with LV HRC fuses must be measured in 3 phases and their power consumption must be allocated to the appropriate cost centers by employing a power manage-ment system.

Meters for these load circuits shall be placed in such a way that they can clearly be allocated to the respective load circuit.

The compensation unit is to be supplied as a choked system.

General pre-conditions

All works are to be announced and registered approx. 4 weeks prior to their start and must be agreed upon with the user/construction management/customer. The speci-fied switchgear dimensions are maximum dimensions. They are binding. Prior to delivery, the contractor shall

take measurements of local conditions (openings and doors for moving the switchgear in, frame dimensions of switchgear, possible transportation units, weights, routes …) in coordination with the construction manage-ment. The delivery of switchgear components shall also cover all costs required for testing and acceptance (power supply network operator, experts..) and additional ser-vices.

The leading products are binding.

The protective devices put out to tender are matched to one another regarding their short-circuit behavior / charac-teristic curves / shutdown behavior. For this reason, all installation devices must be procured from one supplier. Protective technology, reliability of supply as well as any possible power feedback into the system in case of an existing standby power network is to be agreed with the network operator / public testing and inspection authori-ties, Association of Property Insurers etc. Any works out-side this industry, if not explicitly mentioned herein, are not part of this performance specification. For the duration of constructions, the contractor shall name a responsible contact person for every work contract section /installation who shall be in charge of coordination and clarification of questions. Participation in construction-related meetings is compulsory. If the contractor employs subcontractors, they shall be named in the tender. The contractor provides coordination, responsibility for and representation of his subcontractors (construction-related meetings, workflow, schedules …). The contractor, and not his subcontractors, shall be the sole point of contact and partner in negotia-tions for the customer.

Schedule

To ensure erection and mounting procedures running on schedule, the contractor must adjust his capacities to the specific mounting situation. Based upon the corner dates listed below, the contractor is required to draw up a de-tailed time schedule which describes the precise erection and mounting procedures. The contractor must proactively lead all coordinating talks required in this context with the various developer representatives, representatives of public authorities and any other performing companies involved in the construction process. The detailed time schedule must be handed over to the developer’s represen-tative 4 weeks after the contract has been awarded, at the latest. The time schedule becomes part of the contract and must strictly be complied with. This time schedule must be actively managed during construction, and, if necessary, adjusted to a changed situation in good cooperation with the parties involved.

Proof of selectivity (medium-voltage utilities substation to final circuit)

Computational proof for the selected protective devices and cable cross sections including an assessment of selec-tivity for the entire supply network (MV branch circuit to


final circuit) including energy balance for all of the con-nected loads (switchgear cabinets for the different supply subsections, e.g. electrical installations, heating, ventila-tion, air conditioning, lighting …).

Data on network configuration (1-pole single-line dia-grams), cable lengths and load data are provided by the construction management.

The outgoing feeder terminals of the above mentioned main distribution boards will be regarded as the interface for selectivity assessment.

Relevant power supply system data shall be handed over to the third-party works suppliers in writing. The point of reference is the feeder terminal to the distribution boards for the different supply subsections.

The proof of selectivity, being the fundamental basis of the implementation planning for mounting the electrical installation, shall be handed in, at the latest, when the implementation plans of the main switchgear are submit-ted for the purpose of obtaining a mounting permit. This proof must include the following:

Energy balance in form of a table

1-pole single-line diagram with device parameters (for power sources, protective devices, cable routes)

1-pole single-line diagram with load flow and voltage drop representation for each circuit

1-pole single-line diagram with representation of the minimum and maximum short-circuit loads

I2t characteristic curve diagrams of all circuit-breakers and the largest LV HRC outgoing fuses for each switchgear station and network(these curves must show the circuit-breaker parameters that have actually been set)

A table of all protective devices including setting ranges and set values (will also be used for subsequent commissioning documentation)

This proof must be produced using an approved, certified IT tool.

Manufacturer/IT tool: Siemens/SIMARIS design

Note:

See Application Manual, Draft Planning, Section 8.3 Selec-tivity and Back-up Protection.

A network calculation should always be performed prior to any performance specification, forming a basis thereof. Any problems resulting from a wrong device selection/combination/arrangement will thus be detected at an early stage.

Furthermore, a network calculation provides a record of planning reliability with regard to cable cross sections, voltage drop, observance of conditions for disconnection

from supply, and the grading distances of protective de-vices.

Selectivity is required on the basis of the following stan-dards, regulations and recommendations:

DIN VDE 0100-718 “Erection of low-voltage installations – Requirements for special installations or locations – Part 718: Installations for gathering of people“ (previously DIN VDE 0108)

DIN VDE 0100-710 “Erection of low-voltage installations – Requirements for special installations or locations – Part 710: Medical locations“ (previously DIN VDE 0107)

Safety Rule of the Nuclear Safety Standards Commission (KTA 3705) Switchgear, Transformers and Distribution Networks for the Electrical Power Supply of the Safety System in Nuclear Power Plants

Increasing (global) customer demand for switchgear with a high degree of supply reliability


In accordance with the Application Manual, Basic Data and Preliminary Planning, Section 5.1 and Part 2 of the Applica-tion Manual, Draft Planning, Section 3.4 Medium-Voltage Switchgear.

An up-to-date template for the tender specification text can be obtained on the Internet at: www.siemens.com/tip/consultant

Note: Pressure calculation for internal faults

This proof is sometimes a mandatory requirement stipu-lated by the power utility.

A calculation gives information regarding pressures pro-duced in case of accidental arcs and provides the resulting dimensions of openings in the shell necessary for pressure relief (which is important when the switchgear room should be located somewhere inside the building, because pressure relief openings would then be problematic).

In accordance with Application Manual, Basic Data and Preliminary Planning, Section 5.1.3 Pressure Development in Switchgear Rooms.

Transformers and accessories

In accordance with the Application Manual, Basic Data and Preliminary Planning, Section 5.2 Distribution Transformers and Part 2 of the Application Manual, Draft Planning, Chapter 4 Transformers.
