Excitation and governor systems play crucial roles in ensuring the precise control and optimal performance of power generation. The excitation system regulates the voltage output of generators by adjusting the field current. It ensures a stable and reliable power supply, while also enabling reactive power control. On the other hand, the governor system manages the speed and power output of the prime mover, such as a turbine or engine, to maintain grid stability and respond to load fluctuations. These advanced systems incorporate sophisticated control algorithms and monitoring capabilities to enhance power generation efficiency and reliability.
