Generator Paralleling Simulator

Auteur:William Haynes

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

Paralleling Procedure
  1. Start the generator prime mover and bring it up to speed.
  2. Adjust the incoming generator to nominal voltage and frequency.
  3. Turn on the synchroscope to the incoming generator position.
  4. Adjust speed until the synchroscope is turning slowly in the fast (clockwise) direction, about 1/10 Hz higher than the bus.
  5. Bring the incoming voltage to slightly higher than bus voltage.
  6. When ready, close the circuit breaker when synchroscope is at the 11:00 position.
  7. First, balance the active (kW) load by making adjustments to the two speed governors. This will have a secondary effect of raising or lowering the frequency and voltage.
  8. When the active loads are perfectly balanced, balance the reactive (kVAR) loads by making adjustments to the voltage regulators. This will have a secondary effect of raising or lowering the voltage, but won't affect the frequency.
  9. Maintain voltage and frequency within the limits while balancing the load.
Use your up and down arrow keys for fine tuning the governor and voltage regulator settings when you're close to balanced. Click the kW and kVAR buttons in the right panel to see the "house diagrams" which display the voltage, frequency and load relationships. You may change the active and reactive loads with the power triangle. This represents the electrical demand on the generators. Try not to overload them.
