Description : What is meant by pumped storage power plant?

Last Answer : The pumped storage plants are used for load balancing. During peak load water is used to work on turbines to produce electricity. Water after working in turbines is stored in the tail race reservoir.

Description : What is power house?

Last Answer : A power house is a stable structure which houses the equipment in the power plant

Description : Write about prime movers?

Last Answer : Prime mover converts the kinetic energy of water into mechanical energy to produce electrical energy. Pelton wheel turbine, Francis turbine, Kaplan turbine and Propeller turbine are prime movers used in hydraulic power plants.

Description : What is the use of spill Ways?

Last Answer : Spillway is like a safety valve of the dam. It discharges major flood without damaging the dam. It keeps the reservoir level below the maximum level allowed.

Description : Explain about penstock?

Last Answer : The pipe between surge tank and prime mover is known as penstock. It is designed to withstand high pressure. It is made up of reinforced concrete. In very cold areas, the penstock is buried to prevent ice formation and to reduce the expansion joints.

Description : What is the function of Fore bay?

Last Answer : Fore bay is considered as naturally provided surge tank. It is temporary water storage when the load on the plant is reduced and provides water for initial increment on increasing load.

Description : What is the use of surge tank?

Last Answer : The surge tank is used to provide better regulation of water pressure in the system. The surge tank controls the water when the load on the turbine decreases and supplies water when the ... variations resulting from the rapid changes in water flow in penstock and hence prevents water hammer.

Description : Why trash rack is used?

Last Answer : The trash rack is used to prevent the entry of debris, which might damage the turbine runners and chock up the nozzle of impulse turbine.

Description : What is the main purpose of the dam?
