Hydroelectric Power Plant Operating Principles

Generators in Hydroelectric Power Plants

Employing the principle of electromagnetic induction, the electric generator transforms the mechanical energy of a rotating turbine shaft into electric energy. Due to the lower rotation frequency of water turbines, generators in hydroelectric power plants are much larger than generators of the same output in thermal power plants.
