Governor:
The governor controls the inflows into the turbines based on the demand of the electrical load. It senses the rotational speed (RPM) of the turbine and changes the flow into the turbines such that RPM remains constant. An increase in RPM denotes an underloading of the turbine and results in the governor restricting the flow to the turbine. A decrease in RPM denotes and overload and results in the governor allowing higher flow to the turbine.
Flow control by governors is achieved through a hydraulically driven oil pressure system, which regulates the turbine valves.
Role of governor in hydropower plant: It is the main controller of the hydraulic turbine. It controls the water flow through the turbine. By controlling the water flow, the RPM is controlled.Last updated on May 28, 2025
