Introduction:
In a typical hydroelectric power generation system, a dam (water reservoir) is built near water body such as a river to create head (height) that enables water to flow at high pressure via a pipe (penstock) to the turbines that drive the power generators. The fast moving water turns the turbine blades at high velocity, and in turn, the turbine turns the electricity generator’s rotor. The wire coils in the generator’s rotor sweep past the stationary coil (stator) in the generator thus producing electricity. This concept was first demonstrated in 1831 by Michael Faraday, who discovered that ...
