Complementary power and frequency control for power generating equipment

Abstract

A controller for a power generating system that includes an engine and a generator, wherein the engine provides mechanical force to the generator, which converts the mechanical force to electrical energy that is distributed via a distribution network. The controller includes a complementary filter that applies a low-frequency response to changes in the monitored power output and a high-frequency response to changes in the monitored grid frequency. The complementary filter combines outputs of the high-frequency response and low-frequency response to generate a process variable. A feedback controller generates a fuel flow value in response to the process variable.
