Modelling and analysis of operation PMSG based WECS under different load conditions

Abstract

The permanent magnet synchronous generator (PMSG) is widely used in wind power generation due to its high energy efficiency and controllability. Unbalance load conditions or different load conditions effects PMSG operation system. Furthermore, these conditions occur in problematic operation and distorted converter currents. The operation condition of the PMSG system to the effects of variation load is observed in this study and the performances of the PMSG based on wind energy conversion system (WECS) are analyzed. Simulation of the whole system using a 850-kW PMSG based on WECS system is built in the Matlab Simulink. The power flow efficiency of a PMSG is implemented to this study and control of the system for WECS. The proposed model is proven to verify under different operation conditions.
