Wind speed Wind turbine Drive train PMSG Sliding mode control

Abstract

The wind energy conversion system for the generation of electricity in variable speed needs the control of speed of permanent magnet synchronous generator in order to maintain its efficiency. Inorder to maintain the efficiency proper control of the generator is necessary. One such promising controlling method is sliding mode control. This control method provides ideal characteristics for the application in the control of permanent magnet synchronous generator. The modeling of the wind energy system and corresponding sliding mode design is done. Application of this method for control using dynamic models of the d axis and q axis currents, the shaft rotational speed is controlled according to the wind speed.
