Engineering · Electrical — Load Sharing
After two AC generators are paralleled, the division of real (kW) load between them is adjusted by:
- AChanging the voltage regulators
- BOpening the bus tie
- CChanging the phase rotation
- DAdjusting the governor (fuel) settings of the prime movers✓ Correct
Explanation
Real power (kW) follows the prime mover input, so kW load is shifted by trimming the engine governors. Reactive (kVAR) load is shared by adjusting the voltage regulators/excitation. The two are controlled independently.
