SIMULATION OF PMSG BASED WIND TURBINE CONNECTED TO GRID

Abstract

In recent years, The advancement of power electronic technology, novel control strategies and new circuit topologies, the grid connected small wind turbine industry is primarily dominated by the permanent magnet synchronous generators (PMSG) have increasingly drawn interests to wind turbine manufactures. This paper presents modeling and control strategy for the grid connected PMSG-based wind turbine systems, where PMSG is used as a variable speed generator. The two mass drive train models is established for coupling the wind turbine and generator , pitch angle control at high wind speed, an LC filter is used at both side of grid side converter for desired power quality. The control scheme is developed for grid side converter to get regulated voltage at grid side. The simulation model is tested in MATLAB/SIMULINK environment.
