| Abstract | ||||
| This paper presents a new control strategy of a stand-alone wind energy conversion system. The proposed system consists of a three pbase induction machine connected to a variable speed wind turbine through a step-up gear box. A current controlled voltage sonrce inverter (CC-VSI) with an electronic load controller (ELC) is connected in parallel with the main load to the AC terminaIs of the induction machine. The proposed control strategy is based on fuzzy logic control principles which enhance the system performance. There are three fuzzy logic PI controllers and one hysteresis cnrrent controller (HCC) which are used to extract the maximum available energy from the wind turbine as well as to regulate the generator terminal voltage simultaneously against wind speed and load variations. A complete mathematical model of the proposed system is developed in order to simulate its performance with the proposed control strategy. Simulation results using MatlabISimulink demonstrate the effectiveness of the proposed contrcl strategy in capturing the maximum available energy Grom the wind turbine and in regulation of the generated terminal voltage simultaneously against wind speed and load variations | ||||
