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.
Claims20
A method for controlling a generator, said generator, coupled with one or more electrical loads, comprising a shaft driven at a speed, 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 method comprising:
- (a) measuring two consecutive speeds, a pre-determined time interval apart, and determining a difference between the speeds to arrive at a rate of change in speed, via a first line;
- and
- (b) varying 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.
A control device for a generator, said generator, coupled with one or more electrical loads, comprising a shaft driven at a speed, 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 sense two consecutive speeds, a pre-determined time interval apart, and determine a difference between the speeds to arrive at a rate of change in speed, 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.
