Abstract
The present invention provides a control system for a power generation system, comprising a generator coupled to a turbine via a shaft. The control system includes a memory storing instructions. The control system also includes a processor coupled to the memory and configured to execute the instructions. When the instructions are executed, the processor receives a direct current (DC) bus voltage from an automatic voltage regulator (AVR), wherein the AVR is configured to control the voltage characteristics of the generator and determine the speed of the generator based on the DC bus voltage.
