Question

What is an induction generator?

Answer 1

Induction machines are sometimes used as a generator. These are known as induction generators or asynchronous generators. So under what conditions will an induction machine will behave as an induction generator?

An induction machine will behave as an induction generator when:

1)Slip becomes negative due to this the rotor current and rotor emf attains negative value.

2)The prime mover torque becomes opposite to electric torque.
