Governor
Electrical Engineering · Mechanical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A governor controls the speed of a prime mover such as a turbine or engine by adjusting the fuel or steam input. It maintains the rotational speed at the setpoint despite load variations.
Example in context
“The hydro turbine governor reduced the gate opening when the generator load dropped to prevent overspeed.”
“Hidro türbin regülatörü, aşırı hızı önlemek için jeneratör yükü düştüğünde kapı açıklığını azalttı.”
Where engineers use it
Governors are critical in power plants for frequency control. Engineers must tune the droop setting to allow proper load sharing among parallel generators.
Synonyms: speed governor, turbine governor
In Mechanical Engineering
A mechanism that automatically regulates the speed of an engine or turbine by adjusting fuel or working fluid supply as load changes. It keeps rotational speed close to a preset value without operator intervention.
“As the generator load suddenly dropped, the governor cut back the fuel rack and prevented the diesel engine from overspeeding.”
Practice: can you use “Governor” at work?
During a sudden islanding event, the turbine overspeeds. Describe how the governor responds and what settings you would check.
Show a model answer
“The governor adjusts fuel flow to keep the turbine at synchronous speed.”
