A wind power excitation synchronous generation system having a maximum power determining unit and a control method thereof are disclosed. In this control method, dual input shafts and a single output shaft of a gear transmission mechanism are used, and two kinds of inputted power, such as wind power and servo motor control power, are integrated, so as to allow the output shaft to drive an excitation synchronous generator to generate electric power. In this system, a rotation speed and a phase of a servo motor are controlled, so as to allow the excitation synchronous generator to output the electric power with a frequency and a phase identical to the utility grid.

Wind power excitation synchronous generation system having maximum power determining unit and control method thereof

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.
