Power control system and method
First Claim
1. A control device for a generator driven by a speed converter, said speed converter coupled with the generator and a prime mover and capable of converting a speed of the prime mover, said generator, coupled with one or more electrical loads, comprising a generator output power controller capable of manipulating an output power of the generator and a generator speed indicator capable of generating a signal indicative of the generator speed, said control device comprising:
- a processor, including a programming code operable on the processor, coupled with the generator output power controller and the generator speed indicator;
wherein said processor is configured to measure a rate of change in speed of the generator, via a first line, and to vary the output power of the generator by applying a speed-control signal to the generator output power controller, via a second line, according to said rate of change regardless of electrical power required by the one or more electrical loads.

Abstract
This invention discloses a power control system comprising a prime mover and a generator driven by the prime mover. A control device is coupled with the generator to ascertain a change in speed of the generator and vary an output power of the generator according to the change. The control device applies a signal to reduce the generator output power and another signal to restore the generator output power. The power control system may include a transmission, a speed converter, and/or an accessory.
