1, asynchronous

(1) the cage asynchronous generator; Power is 600/125 kw to 750 kw 800 kw to 12500 kw

The stator of different power to the grid frequency 50 hz alternating current (ac);

(2) wound rotor doubly-fed induction generator; The power of 1500 kw

To grid 50 hz alternating current, the stator rotor controlled by frequency converter, indirect transmission active or reactive power to the grid.

2, synchronous

(1) permanent magnet synchronous generator; Power of 750 kw to 1200 kw to 1500 kw magnetic field produced by permanent magnets, stator output after full power rectifier inverter to the grid frequency 50 hz alternating current

(2) electric excitation synchronous generator; By outside received dc current magnetic field on the rotor, stator output after full power rectifier inverter to the grid frequency 50 hz alternating current

According to different leaf form, the existing wind generator is divided into the following two categories:

3, horizontal axis

Currently used in the world the most form, the most powerful about 5 mw.

4 and the vertical shaft

At the beginning of the 21st century by China, Japan, Europe invented a new type of wind turbine, almost at the same time different from the first vertical axis wind turbine (e), efficiency is higher than that of horizontal axis wind turbines, no noise and steering mechanism, and simple maintenance. The first choice for small and medium-sized wind turbine has become the European and American market. At present the most power in the world is composed of HaiMo electronic equipment co., LTD. (MUCE) production of 50 kw vertical axis wind turbines, Japan's most powerful 30 kilowatts, Anglo-American countries produce power between 1 kw and 10 kw.
