A governor is the component of the steam turbine control system that regulates the rotational speed in response to changing load conditions. The governor output signal manipulates the position of the steam inlet valve or nozzles which in turn regulates the steam flow to the turbine. The governing of the turbine is necessary as a turbine is directly coupled to an electric generator which is required to run at a constant speed under all fluctuating load conditions
In a steam turbine, there are three types of governors are used.
Throttle Governing of Steam Turbine
Nozzle Control Governing Of Steam Turbine
Bypass Governing of Steam Turbine.
