ABSTRACT:
Prior power generation systems generated output voltages having relatively large, undesirable overvoltage transients due sudden load reduction. In order to overcome this disadvantage, a power generation system for generating a DC bus voltage on a DC bus is provided with a switch coupled across the DC bus to suppress overvoltage transients. The power generation system includes a synchronous generator that generates AC power and a rectifier that rectifies the AC power to produce DC power and supply the DC power to the DC bus. A voltage regulator controls magnitude of the DC bus voltage by varying the amount of current provided to a field winding associated with the synchronous generator. A switch is coupled across the DC bus and is repeatedly switched when the DC bus voltage reaches a predetermined magnitude. When the switch is in operation, the voltage regulator controls the DC bus voltage based upon an emulated voltage generated by a voltage emulator.
