5.2 Medium Voltage System5.2.1 Electric Power Demand:

The estimated electrical power demand of the entire building, including the lobby areashas been derived in compliance with the recommendations of CIBSE and based uponthe following assumptions; Diversity Applied: 0.6 (For Public, commercials); 0.4 (For Bed rooms) Transfomer spare Capacity: 10% for transformer will be applied (see calculation

sheet in appendix 2 for reference). Restaurant kitchens : Central LPG 100% back-up power for whole building

See Appendix for Calculations5.3 General Power Supply and Transformers:

Sources of Power Supply for the project will mainly from: City lines and transformers Standby Diesel Power Generators of the building

The Power Sub-station connected to City Power Supply will be located at ground floor andgenerally consist of:

5.3.1 The Medium Voltage Power System

Under normal conditions the proposed Power Supply for the building will be derived fromthe City power line and will comprise two medium voltage 22kV feeders which will formpart of a City owned ring main.

Cable sizes and types associated with the MV supply will be 24 KV ratedXLPE/PVC/SWA/PVC 240mm2 cables and will be installed in uPVC pipe. (Note: therating of Medium Voltage Line should be confirmed by EVN, local electric network)

The cables will terminate into medium voltage switchgear which will be generally LoadBreak Switches that are SF6 switchgear recommended by Accor’ comments rated at24kV and 630A, but set to suit the estimated building load. The switchgear willincorporate all necessary metering and protection relays.

Power to the building will then be distributed via 22KV / 0.4 KV 3P 4W 50Hz cast resindry-type (1250 kVA) step down voltage transformer(s) which will be housed within thebuilding. The transformer(s) will be complete with over temperature sensors which willopen their respective protective device(s) as required under fault conditions.


19/81



Both the MV switchgear and step down transformers will require housing withindedicated rooms which require a fire rating of ninety minutes.

The medium voltage system will also be complete with a dedicated earthing systemwhich will comprise a network of electrodes, cabling and copper earth bars as required.Resistance to earth will be 1ohm.

5.3.2 The Power Back-up System – Diesel Engine Power Generators:Under loss of normal power conditions the building power supply will be derived fromprivate stand by diesel power generator of 1000 kVA.

The diesel generator(s) will automatically start in the event of a power failure. Thegenerator(s) will provide power to the building within 10 seconds of loss of supply via an Automatic Transfer Switch (ATS).

The generator will be sized to provide 100% backup power for the building

The fuel oil tank for the generators will be at basement level and will provide 1 day ofdiesel storage.

5.3.3 The Fuel System for Diesel Engine Power Generators A fuel storage tank of 5,000 litres for 24Hrs at basement with the fuel pumps &

pipework system. Fuel from these fuel tanks will be pumped automatically to the generators. The day tank will be mounted on ground inside R.C wall enclosure. The storage tank will be located within an R.C chamber filled with sand. Any fuel leakage will require comtaining within the R.C chamber and will not leak to

the ground.

5.4 Low Voltage System

Low voltage for the building will be distributed at 380V and 50Hz derived via the mediumvoltage system and the step down transformers. The transformers will supply a main
