2.25 FUNCTIONAL SEQUENCE OF OPERATIONS

A. The EPS Automation shall be provided with the following Modes of Operation:

1. Automatic/Standby Mode

a. The utility main breaker is closed serving utility power to the generator/load bus.

b. The generator main breakers are open.

c. The automation is standing by to act in response to a utility failure.

2. Emergency Modea. Utility Failure

1. Utility protective relaying senses utility voltage or frequency out of tolerance.

2. The utility main breaker is opened.

3. A run request is sent to the generator plant.

4. The first generator up to voltage and frequency is closed to the bus.

5. 26[With Generator Bus Tie Breaker] The generator bus tie breaker is closed.

6. The remaining generators are synchronized and paralleled to the bus as they

come up to voltage and frequency.

7. The system is now in Emergency Mode.

b. Utility Restoration and Exit from Emergency Mode

1. Utility protective relaying senses utility voltage and frequency within tolerance.

2. Following an adjustable time delay (which can be abbreviated by the operator) to

assure that the utility power source is stable, the generator plant is passively

synchronized and paralleled to the utility source by closing the utility main breaker.

3. The generator plant is soft ramp unloaded until the utility source is nominally

serving the entire system load.

4. The generator breakers are opened.

5. The generators are allowed to run for their programmed cool down period.

6. The system is now back in Automatic/Standby Mode.

3. Transfer to Emergency Mode

a. Entry1. The operator places the System Mode Selector Switch into the Closed Xfer to

Emergency position.

2. A run request is sent to the generator plant.

3. The first generator up to voltage and frequency is closed to the bus at no load.



40/49

4. The remaining generators are synchronized and paralleled to the bus at no load as

they come up to voltage and frequency.

5. When all generators are on the bus they are soft ramp loaded until the generator

plant is serving nominally the entire load on the bus and the utility main breaker is

opened.

--27OR-

5. [With Generator Bus Tie Breaker] When all generators are on the bus, they are

paralleled across the generator bus tie breaker. They are then soft ramp loaded

until the generator plant is serving nominally all of the load on the bus and the utility

main is opened.

6. The system is now running in Emergency Mode.

b. Exit from Emergency Mode

1. The operator removes the System Mode Selector Switch from Transfer to

Emergency position and returns it to the Auto position.

2. Following an adjustable time delay (which can be abbreviated by the operator), the

generator plant is passively synchronized and paralleled to the utility source byclosing the utility main breaker.

3. The generator plant is soft ramp unloaded until the utility source is nominally

serving the entire system load.

4. The generator breakers are opened.

--OR-

4. [With Generator Bus Tie Breaker] The generator bus tie breaker is opened and then

all of generator breakers are opened.

5. The generators are allowed to run for their programmed cool down period.

6. The system is now back in Automatic/Standby Mode.

4. Load Management Mode

a. Entry

1. Select one of the modes of operation:

i. Import Limit - The user places the Import/Export toggle switch in the Importposition and places the Base Load/Utility Tracking toggle switch in the Utility

Tracking position. The user sets the Utility Import Set point to the desired

amount of kW that they want to import through the Utility Circuit Breaker

during Load Management Mode.

ii. Export Limit - The user places the Import/Export toggle switch in the Export

position and places the Base Load/Utility Tracking toggle switch in the Utility

Tracking position. The user sets the Utility Export Set point to the desired

amount of kW that they want to export through the Utility Circuit Breaker

during Load Management Mode.

iii. Base Load Import - The user places the Import/Export toggle switch in the

Import position and places the Base Load/Utility Tracking toggle switch in the

Base Load position. The user sets the Base Load Set point to the desired

amount of kW that they want the generator plant to assume during Load

Management Mode. The controls will not allow the generator plant to export



41/49


42/49

1. The Utility Fail Test Switch is placed in the ON position.

2. Voltage sensing at the utility protective relay is opened, which simulates a loss of

utility.

3. The system enters into Emergency Mode as described in the Emergency Mode

sequence above.

b. Exit from Utility Fail Test Mode1. The Utility Fail Test Switch is placed in the OFF position.

2. Voltage sensing at the utility protective relay is restored, which simulates the

return of utility power.

3. The system exits from Emergency Mode as described in the Emergency Mode

sequence above.

electrically operated. Each electrically operated distribution circuit breaker shall be

field selectable to be assigned to any of the available Load Shed Priority Levels.

i. Shed Delay Timer, adjustable from 0 to 1024 seconds

ii. Add Delay Timer, adjustable from 0 to 1024 seconds

iii. Load Shed Override Selector (shed/auto//add)iv. Status indicators to show whether the Priority Level is Added or Shed

2. Provide the following controls for each Non-Essential Load Shed Priority

i. Load Shed Override Selector (shed/auto//add)
