چکیده مقاله :
In recent years, there has been a fast growth in wind energy conversion system (WECS). There are two general types of wind turbines in WECS: fixed speed wind turbines and varying speed wind turbines.Permanent magnet synchronous generator (PMSG) is one of the most attractive generators for the varying speed turbine WECS.In this paper, a fuzzy controller is proposed to control the current source inverter (CSI) in a wind energy conversion system (WECS) based on permanent magnet synchronous generator (PMSG). The fuzzy controller guarantees the unity power factor operation of CSI. In order to drive CSI the space vector switching (SVM) is utilized. In addition, the WECS has a buck converter which regulates the DC current so that the maximum power point tracking is achieved. The proposed system is implemented in MATLAB/SIMULINK, and the results are provided and compered with the traditional PI controller based systems. The results show that the proposed system is faster than traditional PI controller based systems.
