Abstract :
In this paper, a control for variable speed Wind Energy Conversion System (WECS) that incorporates a Permanent Magnet Synchronous Generator (PMSG) is described. The proposed approach is based on a Vector Control theory (VC) for regulate of both grid-side and machine converters of a PMSG wind turbine. Then, an optimal control strategy is developed for integrated control of PMSG power extraction. It combines Space Vector Modulation (SVM) and Maximum Power Point Tracking (MPPT) control strategy to maximize the generated power from Wind Turbine Generator (WTG). A pitch control scheme for variable speed WTG is proposed to limit the output power produced by the turbine. Therefore, WECS can not only capture the maximum wind energy, however also can maintain the frequency and amplitude of the output voltage with unity power factor. Finally, the effectiveness of the novel control strategy is verified by simulation using Matlab/ Simulink environment. Simulation results have shown the effectiveness of the proposed control strategy for WECS based on the PMSG.
