A wind power excitation synchronous generation system 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 energy, such as wind energy 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. Furthermore, a control circuit for maximum power tracking is used to control an excitation current of the excitation synchronous generator for achieving a stable voltage, the maximum outputted wind energy and the minimum energy consumption of the servo motor. |
