CHAPTER 9 HYDRO GENERATOR, CHARACTERISTICS AND

CHAPTER 9 HYDRO GENERATOR, CHARACTERISTICS AND PERFORMANCE 9.1 GENERAL The electric generator converts the mechanical energy of the turbine into electrical energy. The two major components of the generator are the rotor and the stator. The rotor is the rotating assembly to which the mechanical torque of the turbine shaft is applied.

Induction generator Wikipedia

An induction generator or asynchronous generator is a type of alternating current (AC) electrical generator that uses the principles of induction motors to produce electric power. Induction generators operate by mechanically turning their rotors faster than synchronous speed. A regular AC induction motor usually can be used as a generator, without any internal modifiions.
