Abstract
A stand-alone wind power generation system and a method for controlling an excitation synchronous generator thereof are provided. In this method, an input wind power is transformed into an electrical power and outputted to a load. With the use of a coaxial configuration, a windmill, a speed-increasing gearbox, the excitation synchronous generator, and a motor are integrated in the same shaft. The output voltage of the generator is stabilized by an excitation field control. With the use of a motor servo control, the speed of generator can be stabilized under a wind disturbance condition. Therefore, the output power and frequency can be stable. A power flow management unit can control battery sets to charge and discharge, so as to accomplish the proposed control method.
