Property compare of two active power controller in wind power generation system

The main problem for variable speed constant frequency wind power generation system is how to improve the dynamic respond as well as stability. In this paper, according to mathematical model of wind power generator and active power separate control strategy with reactive power, PI controller and fuzzy controller were used separately in the control link of active power. And active power fuzzy controller was designed. In MATLAB/Simulink, doubly-fed wind power generation systems controlled by two kinds of controller were simulated and their properties were compared, it is shown that wind power generation system based on fuzzy controller has capacity to better dynamic respond and disturb resistance.
