How Asynchronous (induction) generators Works ...???

Introduction        Most wind turbines in the world use a so-called three phase asynchronous (cage wound) generator, also called an induction generator to generate alternating current. This type of generator...

What is the Difference between synchronous generator and induction generator ...???

Difference between synchronous generator and induction generator In a synchronous generator, the waveform of generated voltage is synchronized with (directly corresponds to) the rotor speed. The frequency of output can be given as f = N * P / 120 Hz. where N is speed ...
