Simulation and Control of WECS with Permanent Magnet Synchronous Generator (PMSG)

This paper discussed the detailed electrical model of gearless variable speed wind energy conversion system (WECS) with permanent magnet synchronous generator (PMSG) to accomplish the optimal power flow and maximum power transfer to the distribution grid. PMSG based WECS system has reduce the hardware complexity of speed regulation and their control so it's more reliable and more efficient than doubly fed induction generator (DFIG) based WECS model. Here all the generating machines, power control devices and turbine models are designed in MATLAB/Simulink tool by their detailed equations. The control algorithm of power converter are support on PWM techniques which is used to confine the maximum power form the wind turbine and also control the active and reactive power flow into the distribution grid to improve the power quality. This paper presents to study the performance of simple and detailed PMSG based WECS to grid connected load or also discusses their performances.
