摘要： The present invention provides an excitation control circuit, a control method using the same and an electrically excited wind power system having the same. The excitation control circuit comprises at least one converter and at least one AC/DC conversion module. The converter is located between an AC electric grid and a wind power generator, so as to convert AC power generated by the wind power generator into AC power corresponding to the AC electric grid. The input side of the AC/DC conversion module is electrically connected between the converter and the wind power generator, and the output side is coupled to an excitation device. The AC/DC conversion module is used to convert the AC power from the wind power generator into a DC voltage, and provides an excitation current for the wind power generator using the DC voltage.

摘要： A wind-power generation system with an over-speed protection is disclosed. The system is provided to convert wind energy into mechanical energy by a wind turbine, and mechanical energy is converted into electric energy by the wind turbine driving a generator. Also, electric energy is delivered to a power grid. The wind-power generation system mainly includes an AC crowbar, a fuse, and a DC chopper. The AC crowbar or the DC chopper is provided to consume superfluous energy outputted from the generator, thus providing an over-load operation to brake the wind turbine when the wind turbine operates under a first stage over-speed operation. Finally, the generator is isolated from the generator-side converter by disconnecting the fuse when the wind turbine operates under a second stage over-speed operation.
