<P> An induction generator connected to a capacitor system can generate sufficient reactive power to operate on its own . When the load current exceeds the capability of the generator to supply both magnetization reactive power and load power the generator will immediately cease to produce power . The load must be removed and the induction generator restarted with either a DC source, or if present, residual magnetism in the core . </P> <P> Induction generators are particularly suitable for wind generating stations as in this case speed is always a variable factor . Unlike synchronous motors, induction generators are load - dependent and cannot be used alone for grid frequency control . </P> <P> As an example, consider the use of a 10 hp, 1760 r / min, 440 V, three - phase induction motor as an asynchronous generator . The full - load current of the motor is 10 A and the full - load power factor is 0.8 . </P> <P> Required capacitance per phase if capacitors are connected in delta: </P>

When does induction motor behave as induction generator
