Hysteresis Band Controller Based Vector Control Of PMSG For Wind Power

Abstract

In the recent years Permanent magnet Synchronous Machines have proved themselves fairly suitable to be used as power generators in variable speed wind energy conversion systems. Due to their high power factor operation and maintenance free operation these machines are gaining attention of researchers and manufacturers. In this paper A PMSG based wind energy system has been proposed, where the PMSG is connected to the grid through two back to back bidirectional converters .This work only emphasizes on the control of the machine side converter and the dc link voltage is assumed to be constant. The machine-side converter (MSC) is controlled by a vector control strategy which employs a conventional PI controller and three hysteresis band controllers for the control of torque and speed. Due to the vector control strategy decoupled control of torque and flux has been achieved in this paper. The whole modeling and simulation has been performed in MATLAB/SIMULINK and the results has been analyzed in the paper.
