Abstract:Due to random fluctuations of wind energy and the characteristics of the wind turbine, the active power output fluctuates with the change of wind speed, which influences the wind generator output power quality. Based on deducing wind power unit transfer function, the stability of wind generator had been analyzed. And in the light of the existing contradiction between the smoothness of output power and the stability of the system, an active power smoothing control method had been proposed, which use a fuzzy controller to self-correct the setting active power of two-stage matrix converter (TSMC) inverter stage. The method give attention to the smoothness of active power output and the stability of wind turbine, which can guarantee wind generator steady operation in wind speed decreasing faster. The TSMC wind power system model had been established in the Matlab/Simulink, simulation results show the feasibility and validity of the method.
