What is the role of Governor in hydro power plant?

The governor in a hydro power plant is a critical control system that regulates the turbine's speed and output by adjusting the flow of water to the turbines. It ensures that the generator operates at the desired frequency and power output, responding to changes in load demand. By maintaining optimal performance and stability, the governor contributes to the overall efficiency and safety of the hydroelectric system. Additionally, it plays a vital role in grid stability by coordinating with other power plants and managing fluctuations in electricity demand.
