PERFORMANCE ANALYSIS OF WIND TURBINE GENERATION SYSTEM AND SIMULATION MODELLING OF WECS WITH PARMANENT MAGNET SYNCHRONOUS GENERATOR

Abstract

In this paper we described  PMSG is a Synchronous Machine, where the circuit of DC excitation  is removed  by permanent magnets, in the place of brushes. PMSG has a  lesser physical size, a lower moment of inertia which means a higher reliability and power density per volume ratio as it has permanent magnets instead of brushes and the slip rings. The electrical losses in the rotor are also eliminated by having permanent magnets in the rotor circuit. The PMSG are becoming an interesting solution for wind turbine applications.
