Generator Paralleling Simulator

Goal: Start and parallel Generator 2. Balance active and reactive loads, while maintaining nominal voltage and frequency.

Paralleling Procedure

Start the generator prime mover and bring it up to speed.
Adjust the incoming generator to nominal voltage and frequency.
Turn on the synchroscope to the incoming generator position.
Adjust speed until the synchroscope is turning slowly in the fast (clockwise) direction, about 1/10 Hz higher than the bus.
Bring the incoming voltage to slightly higher than bus voltage.
When ready, close the circuit breaker when synchroscope is at the 11:00 position.
Balance the active load by making adjustments to the governors. This will have a secondary effect of raising or lowering the frequency and voltage.
Balance the reactive load by making adjustments to the voltage regulators. This will have a secondary effect of raising or lowering the voltage.
Maintain voltage and frequency within the limits while balancing the load.

You may change the active and reactive loads with he power triangle. This represents the electrical demand on the generators. Try not to overload them. Click the Specifications button to see the "house diagrams" which display the voltage, frequency and load relationships. You can use your up and down arrow keys for fine tuning the governor and voltage regulator settings.
