NORMAL OPERATION (UTILITY POWER IS AVAILABLE):

· GENERATORS 1 AND 2 ON STANDBY.

·· 52L CLOSED (THIS IS THE ISOLATION SWITCH THAT IS LOCATED

AT/ADJACENT TO THE TURBINE GENERATOR).

·· GENERATOR BREAKERS OPEN (THESE ARE THE AUTOMATED

BREAKERS LOCATED INSIDE EACH GENERATOR).

·· GENERATOR CONTROL PANEL MONITORS POWER FLOW AT UTILITY

INTERFACE.

LOSS OF UTILITY POWER (NORMAL POWER IS LOST FROM UTILITY PROVIDER):

· GENERATOR CONTROL PANEL DETECTS LOSS OF POWER AT UTILITY

METERING CABINET.

·· OPEN 52L RELAY. SIGNALING GENERATOR CONTROL PANEL TO

BEGIN GENERATOR START-UP. DISCONNECTS CAMP ISOLATE AWAY

FROM UTILITY.

·· THE GENERATOR CONTROL PANEL SENDS START SIGNAL TO

NATURAL GAS TURBINE GENERATOR.

·· NATURAL GAS TURBINE GENERATOR BEGINS STARTUP.

·· THE GENERATOR CONTROL PANEL SENDS START SIGNAL TO

NATURAL GAS GENERATOR.

·· THE GENERATOR CONTROL PANEL MONITORS NATURAL GAS

TURBINE GENERATOR AND NATURAL GAS GENERATOR FOR

PROPER POWER OUTPUT.

·· GENERATORS ARE INDEPENDENTLY SYNCHRONIZE WITH

GENERATOR PANEL PP-GEN. ONCE ONE GENERATOR IS FEEDING

PANEL PP-GEN, GENERATOR CONTROL NOTIFIES PLC. PLC DIRECTS

52L TO CLOSE, PROVIDING EMERGENCY POWER TO BASE.

·· ONCE NATURAL GAS GENERATOR IS UP TO SPEED. NATURAL GAS

TURBINE GENERATOR TO BEGIN SHUTDOWN CYCLE.

·· GENERATOR CONTROL PANEL CONTINUES TO MONITOR POWER

OUTPUT OF GENERATOR THAT IS OPERATING.

THIS IS THE STANDARD OPERATION UNTIL UTILITY POWER IS RESTORED.
