Abstract: In this paper,the five VSCF(variable speed constant frequency)wind power generation systems,such as cage asynchronous generator,permanent magnet generator,AC excited double-fed generators,brushless doubly-fed generators,magnetic field modulation type generator were introduced firstly.Then their merits and draw backs were analysed and gave out the future trends of VSCF wind power generation system.
