FULL ELECTRICAL STRATEGY CONTROL OF WIND ENERGY CONVERSION SYSTEM BASED PMSG

Abstract

This paper is devoted to the study and control of high power wind energy conversion system (WECS) based on direct driven permanent magnet synchronous generator (PMSG) connected to electrical grid. So, the WECS contains a three blade horizontal wind turbine, PMSG with high number of pole and PWM (pulse width modulation) full power converter. In partial load region, the generator side converter is controlled by means of sensorless fuzzy maximum power point tracking (MPPT) algorithm. In case the WECS rated power is reached, power is limited via generator torque control, so without pitch control. Simulation results under Matlab \ Simulink® are presented in order to validate the approach.
