What is the function of "Speed Governor" in steam turbine? How it works?..

The control of a turbine with a governor is essential, as turbines need to be run up slowly, to prevent damage while some applications (such as the generation of alternating current electricity) require precise speed control. Uncontrolled acceleration of the turbine rotor can lead to an overspeed trip, which causes the nozzle valves that control the flow of steam to the turbine to close. If this fails then the turbine may continue accelerating until it breaks apart, often spectacularly. Turbines are expensive to make, requiring precision manufacture and special quality materials.

What is the function of "Speed Governor" in steam turbine? How it works?..

Answer / k.sankar

Governor has two valves one is TTV-Trip and Throttle
valve,second one is governor control valve.
Speed governors may used to control the speed of the steam
turbine.It's such a way set to operate with in minimum and
maximum speeds.
After opening the throttle valve the turbine develops speed.
After a certain speed attains the governor takes the control
and opens the governor valve to increase speed.
