Which type of generators are used in hydro power plants?

Synchronous generators and induction generators are used to convert the mechanical energy output of the turbine to electrical energy. ... will vary significantly depending on the shaft and bearing system, unit speed, ventilation type, rotor dimensions, and characteristics of the driving hydraulic turbine. read more

Salient pole Synchronous generators are used in hydoelectric plant because: The majority of hydroelectric installations utilize salient pole synchronous generators. Salient pole machines are employed because the hydraulic turbine in the hydroelectric plants operates at low speeds compared to steam plants, therefore generators in hydro plant requires large number of field poles to produce the rated frequency. read more

The sizes of hydropower plants are described below. Impoundment. The most common type of hydroelectric power plant is an impoundment facility. An impoundment facility, typically a large hydropower system, uses a dam to store river water in a reservoir. read more
