摘要
Disclosed is a non-grid-connected wind turbine generator system with high power, low cost and high efficiency. The wind turbine generator system includes a wind rotor, a generator and a tower. The wind rotor is a fixed-pitch variable-rotation-speed wind rotor, the wind rotor shaft directly drives a rotor of the generator, and the generator is a power-controlled DC generator, a double-salient brushless DC generator, or a double-stator double-salient brushless DC generator. The rotation speed of the fixed-pitch wind rotor is directly controlled by a power-controlled generator and thereby the attack angle of wind rotor blade is controlled. When wind speed is greater than rated wind speed of the system, the wind rotor is controlled into a state of blade stall so as to limit power output of the wind rotor and effectively broaden the wind speed range of wind rotor.
