① Hold the MSES in an ENABLE position until the selected USI indicator energizes. The switch
returns to the center position when released. This sets the PU networking address and enables the control and monitoring.
② No more than one of each indicator can be on for multi-PU operations. The light on should match
USS position. The USI light will de-energize after the SMS has been in OFF for 3 seconds.
③ With the SMS in AUTO any generator started, manually or automatically, will automatically
parallel to the bus. To prevent the generator from paralleling to the bus put the generator’s breaker in the Pull-To-Lock position.
NOTE: The automatic economizing feature will shutdown one generator every 3 minutes until the system load is at or below the 360KW/450KVA per generator threshold.
WARNING
b. At A-unit, observe Generator 1 automatically starts and accelerates to operating voltage and frequency.
c. At A-unit, observe Generator 1 automatically closes to the system bus.
d. At A-unit, observe the Tie breaker automatically closes.
e. At B-unit, observe the Tie breaker automatically closes.
f. At A-unit, observe Generator 2 automatically starts and accelerates to operating voltage and
frequency.
g. At A-unit, observe Generator 2 automatically parallels to the system bus.
h. At B-unit, observe Generator 1 automatically starts and accelerates to operating voltage and frequency.
i. At B-unit, observe Generator 1 automatically parallels to the system bus.
j. At B-unit, observe Generator 2 automatically starts and accelerates to operating voltage and
frequency.
k. At B-unit, observe Generator 2 automatically parallels to the system bus.
l. Ensure generators have assumed load.
n. Observe the KW, PF and KVAR of each generator at the LCP.
Note: If adjustment is needed for KVAR balance, start with the generator that is the furthest from the average KVAR (either too low or too high). Make minor adjustments of the Voltage Adjust Rheostat (VAR) until the KVAR sharing between generators are within +/– 10% of the average plant KVAR load. This adjustment will typically be required only once during initial power plant setup and is intended to compensate for meter variations among generators.
CAUTION
Improper adjustment of the VAR can cause a reverse KVAR shutdown of a generator.
5.4.5 PLANT OPERATIONS (AUTOMATIC MODE)
5.4.5.1 PRECAUTIONS AND WARNINGS
This mode of operation places control of all generator starting, stopping, synchronizing, and load management under the auspices of the Programmable Logic Controller (PLC) system. As long as the
The master controller (the designated “A” unit) will control all connected generators based on the total system KW/KVA load. The controller shuts down one of the generators after 3 minutes should the system load drop below a level where the remaining generator load would not exceed 85% (360kW) if a generator is shutdown. If the load of the remaining generator exceeds 85% (360kW) for one minute, a standby generator is started and paralleled to the bus. A change of system load is recognized by the control system and appropriate action is taken to maintain generator load in the 85% (360 KW/450 KVA) range. The system never automatically shuts down the final generator under normal operating conditions. The shutdown of the final generator must be done following manual operating procedures. The default configuration is Economizing Mode on. The economizing mode can be turned off from the ORT. Through the ORT, the AUTO shut down is disabled but the AUTO start-up remains active to prevent overloading the online generator(s).
5.4.5.3 DEFAULT OPERATING SEQUENCE
Start-Up Sequence: The automatic controls will continuously monitor the system load. As load on the
system increases, the controls automatically start and place additional units on line in the following sequence at 1-minute intervals:
a. One generator from PU “B” based on lower engine runtime. b. Remaining generator from PU “A”.
c. Remaining generator from PU “B”.
Shutdown Sequence: Based on the loading experienced, the controller shuts down generator sets that
are not needed. For the purpose of explanation, we will assume that all generator sets are on line following an initial startup. Based on load, the controls shut down generator sets in the following sequence at 3-minute intervals:
a. One generator from PU “B” based on higher engine runtime. b. One generator from PU “A” based on higher engine runtime. c. Remaining generator from PU “B”.
5.4.6 POWER PLANT TEARDOWN
5.4.6.1 SHUT DOWN GENERATORS
a. Unload all generators by opening all feeder breakers. This must be done locally from the LCP or ORT.
b. Open both generator breakers using the respective BCS switches.
c. Place both generators in cooldown by placing both ECS switches in STOP/COOLDOWN. d. Allow all engines to complete cooldown and shut down (5 minutes).
e. Place all ECS switches in OFF/RESET.
f. Pull out the DC Control Power breaker on the PU.
NEVER REMOVE POWER CABLES BY HAND, USE HOT STICK AND HIGH VOLTAGE GLOVES. NEVER TOUCH A HIGH VOLTAGE LEAD OR TERMINAL UNTIL IT HAS BEEN DISCHARGED TO GROUND. FAILURE TO OBSERVE THE WARNING MAY RESULT IN DEATH BY ELECTROCUTION.
CAUTION
ALLOW ALL OPERATING ENGINES TO SHUT DOWN AND COOL DOWN COMPLETELY.
a. Disconnect the (A)(B) communication cables from between the PUs, Reinstall the communication cable receptacle covers and store inside the PUs (one per unit).
b. Disconnect the ORT cable and store it in the ORT case. c. Close and latch the ORT port on the PU.
d. Disconnect all load cables used in operation of the PUs.
5.4.6.3 DISCONNECT FUEL LINES
a. Turn all fuel system valves to the off position.
b. Disconnect the fuel hose from the PU fuel connection and the fuel supply. c. Drain any fuel from the hoses into an auxiliary fuel supply and store the hoses.
5.4.6.4 DISCONNECT GROUNDING
a. Remove ground connections from the PU and store with the ground rod.
b. Disconnect the parking stations from the ground grid.
c. Remove the parking stations from their operating positions and reinstall them in their
transportation locations on the inside of the PU rear side access doors.
5.4.6.5 PREPARE PU FOR TRANSPORTATION
a. Reinstall the four radiator splashguards (PU-810B only). b. Verify DC Control power is off.
c. Close and lock the LCP access doors. d. Close and lock all PU side doors.
