Governor and speed regulation:
View all questions of this test
The function of the governor is to keep the speed constant when the load on the turbine increases or decreases.
As the load changes, the governor changes the rate of flow of water to bring the speed back to normal speed and maintains a balance between the power output and input.
A good speed regulating governor should be quite sensitive to the changes in shaft speed and should be rapid in action.
Speed regulation of Pelton turbines:
The speed regulation of a Pelton turbine is obtained by the to and fro motion of a spear inside the nozzle. This motion changes the cross-sectional area, thus regulating the flow of water according to the load.
To avoid water hammer, a double-speed regulating system using a spear and a deflector is mostly used.
A spear or needle is so arranged that it can move forward or backwards, thereby decreasing or increasing the annular area of the nozzle passage. This spear nozzle regulates the water flow through the nozzle.

Regulation of a Pelton turbine is done by changing the annular area of the nozzle. This is because the annular area of the nozzle determines the amount of water that is allowed to flow through the nozzle and strike the turbine blades. Here are some details about how the regulation of the Pelton turbine is done:
• What is a Pelton turbine? - A Pelton turbine is a type of hydraulic turbine that is used for generating electricity. It operates on the principle of impulse, where the water strikes the turbine blades and the energy is transferred to the rotor.
• Why is regulation necessary? - The amount of power that can be generated by the Pelton turbine depends on the amount of water available and the head (pressure) of the water. However, the amount of water that is available can vary depending on the season and other factors. Therefore, it is necessary to regulate the flow of water in order to maintain a constant power output.
• How is regulation done? - The regulation of the Pelton turbine is done by changing the annular area of the nozzle. The nozzle is the part of the turbine that directs the water towards the blades. By changing the annular area of the nozzle, the amount of water that is allowed to flow through the nozzle and strike the turbine blades can be controlled. This, in turn, affects the power output of the turbine.
• Other methods of regulation - In addition to changing the annular area of the nozzle, there are other methods of regulating the Pelton turbine. These include adjusting the speed of the turbine and adjusting the amount of water that is allowed to flow into the turbine. However, changing the annular area of the nozzle is the most common method of regulation.
In conclusion, the regulation of a Pelton turbine is done by changing the annular area of the nozzle. This allows the amount of water that is allowed to flow through the nozzle and strike the turbine blades to be controlled, which in turn affects the power output of the turbine.
