5.2 Assumption of Calculation
The following assumptions are used for the calculation:
1. Two GEGs are considered as the main power supply for normal and emergency loads. The GEGs shall be synchronised and parallel supply the power to the main bus. Thus, each GEG shall be capable to supply 50% of the total load.
2. One EDG is considered as the alternative power supply in case of emergency or maintenance of the GEG, the EDG shall be capable to supply the emergency load.
3. All GEGs are applied for peak load application, then the GEGs shall be classified
as a prime duty operation.
4. The EDG is applied for emergency load application, then the EDG shall be classified as a standby duty operation.
5. The power generator and distribution system shall have at least 20% spare
capacity above the peak load.
6. The generators shall be designed to operate at the maximum ambient temperature of 45°C.
7. The 20% safety factor will be applied for Low Voltage Switchgear sizing.
8. Voltage drop during the starting of the largest motor in the system. This is checked
by using per unit impedance method of calculations and is limited to 15% of the nominal voltage at the connected busbar.

Hence 2 nos. 1000A Charger or the nearest available rating may be selected.
Input capacity of internal charger based on the following table of calculation is
• P.F (Power factor at full load) = 0.85
• η(Efficiency) = 0.9
• UPS input capacity (kVA)= output power/(P.F xη)
= 288 kVA
Hence 2 nos. internal charger rated input 288kVA or above may be selected.
8.0 CONCLUSION AND RECOMMENDATIONS
Based on the above calculation result, the proposed equipment sizing are as follows:
Minimum rating of gas engine generator is 906kVA /725kW on site. The GEGs shall be classified as continuous duty operation. Minimum rating of emergency diesel engine generator is 900 kVA /720kW. The EDG shall be classified as a prime duty operation The rated output power of 24VDC shall be estimated as 7.5kW. The 24VDCUPS comprise 2 sets of battery banks (Model 7OPZV490AH) and 2 sets of battery charger which output current is 315A.
The rated output power of 230VAC UPS shall be estimated as 100kVA. The 230VACUPS comprise 2 sets of battery banks (Model 16OPZV2000AH) and 2 sets of battery charger which output current is 1000A.

Indication & measurements
Operating mode (float / boost / initial)DC total currentBattery voltage and currentAC Rectifier line power voltage and current Battery temperature (with optional sensor)Time left in battery operation with current load (option only with advanced battery monitoring)Event log with date / time (operating mode changes and alarms)
Human-machine interface (front panel)
The system panel shows the system’s current state of operation (which part of the system is currently supplying the load and which is in stand-by mode). LEDs also indicate possible faults.
Operations for turning on and off the system and a lamp test button for checking whether all LED indi-cations are functioning properly. To shut down the system, you have to press the ON and OFF buttons at the same time.
The display unit consists of an LC display, an alarm LED, an acoustic alarm and a keypad. From here, the user can set operational parameters, obtain current measurement data, and access the event and alarm logs.
On the alarm indication panel, the respective LEDs light up to indicate a possible fault or after an alarm has occurred.

The front panel includes a comprehensive and flexible human-machine interface. It is divided into four sections:
Operational parameters
Selectable second display languageAuto startBypass operationBoost chargeAuto boost (charge)Battery capacity testBattery monitor test (optional)Set date / time
Measurements
Load in % of nominal kVA ratingAC rectifier line power 1 voltage and currentAC bypass line power 2 voltageDC total current, battery voltage and currentBattery temperature (with optional sensor)AC Inverter currentAC output voltage, current and frequencyAC output peak currentTime left in battery operation with current load (optional with programmed battery data)Event log with date and time (operating mode changes and alarms)
Human-machine interface (front panel)
The system panel shows the system’s current state of operation (which part of the system is currently supplying the load and which is in stand-by mode). LEDs also indicate possible faults.
Operations for turning on and off the system and a lamp test button for checking whether all LED indi-cations are functioning properly. To shut down the system, you have to press the ON and OFF buttons at the same time.
The display unit consists of an LC display, an alarm LED, an acoustic alarm and a keypad. From here, the user can set operational parameters, obtain current measurement data, and access the event and alarm logs.
On the alarm indication panel, the respective LEDs light up to indicate a possible fault or after an alarm has occurred.
