The Electromagnetic Field Analysis Of Mega-watt Permanent Magnet Synchronization Wind Turbine Generator

In this paper analyses and calculate electromagnetic field about mega-watt PM(permanent magnet) synchronization wind turbine generator,checkout electromagnetism performance, provide reference gist for design, ensurance permanent magnet security. First introduce analysis method about electromagnetic field, compute electromagnetic field using tradition way, give out compute process and result . Secondly , bring forward trait of mega-watt permanent magnet synchronization wind turbine generator and FEM(finite element method) analysis method, imitate and compute multi-model function state by FEM software. Thirdly , compare rating data to upwards two method ,explain excellence of FEM method. Finally give out optimize thought . In text , carry through imitate by ANSYS, offer program list.Through result , veracity and convenience about FEM is better than tradition field-convert-rote method , accord with fact better .
