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.

Claims

1. A power control system, comprising:

(a) a generator comprising a generator output power controller capable of manipulating an output power of the generator;

(b) a prime mover coupled with the generator and operative to drive the generator, said prime mover comprising a prime mover speed indicator capable of generating a signal indicative of the prime mover speed; and

(c) a control device coupled with the prime mover speed indicator and output power controller;

wherein said control device is configured to ascertain a rate of change in speed of the prime mover, via the prime mover speed indicator, and to vary the output power of the generator, via the generator output power controller, according to said rate of change.

2. A method for controlling a power control system, said power control system comprising a prime mover coupled with a generator and operative to drive the generator, said prime mover comprising a prime mover speed indicator capable of generating a signal indicative of the prime mover speed, said generator comprising a generator output power controller capable of manipulating an output power of the generator, said method comprising:

(a) ascertaining a rate of change in speed of the prime mover via the prime mover speed indicator; and

(b) varying the output power of the generator, via the generator output power controller, according to said rate of change.
