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.

Section 1 TOTAL 1504

Uncorrected Amp-Hour capacity of Battery =1504 Ah

Considering ageing and design margin factors, corrected size =1504x0.96x1.1x1.25

=1985AH

Hence each battery bank (Model 16OPZV2000AH) are selected. The UPS has 2 nos Battery bank.




7.6.9 Charger sizing calculation

From Project Specification, The UPS configuration is Redundancy. Each charger unit shall be capable to handle 125% of peak loads in additional to fully recharge the 2x50% battery, following a discharge at peak load for the autonomy time of 6 hours. The minimum required charger rated output(I1)

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.

The front panel, which is identical for both AC and DC Systems, includes a comprehensive and flexible human-machine interface.It is divided into four sections:

Operational parameters

Selectable second display languageAuto startCharge mode (float / boost / initial)Auto boost chargeBattery capacity testAdvanced battery monitor test (optional)Set date / time

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.
