| Abstract: | By using ANSOFT electromagnetic field software,two-dimensional transient finite-element model of direct-drive permanent magnet wind generator is established based on Maxwell,and no-load performance and various sudden short circuit analyses were taken for MW grade direct-drive permanent magnet wind generator. Through theoretical analysis and simulation results verification,maximum armature current has been got in various fault conditions and initial condition of the maximum armature current has been received. It provides theoretical basis for determining the working point of permanent magnets of permanent magnet motor design. |
