A natural waterfalls, 50 meters high, constantly discharges 1.3m3 per second. A mini hydroelectric plant is to be constructed at the bottom of the waterfalls. Calculate the electric generator kW rating, assuming 90% mechanical to electrical conversion efficiency and water turbine design efficiency of 70%.
Synchronous Generator
In comparison to an asynchronous generator, it is a machine where the rotor speed is equal to the rotating magnetic field produced by the stator, i.e., mechanical speed is equal to the electrical speed, thus called synchronous, and not asynchronous.
Salient Pole Rotor
Salient pole rotor includes a large number of exposed poles mounted on a magnetic wheel. The construction of a bright pole is as shown in the image on the left. The proposed poles are made of metal laminations. The rotor winding is provided on these poles and is supported by pole shoes.
