摘要
利用ANSOFT电磁场软件,建立了基于Maxwell的直驱永磁风力发电机二维瞬态有限元模型,对MW级直驱永磁风力发电机进行了空载性能和各种突然短路分析。通过理论分析和仿真结果验证,得到了各种故障工况下所能得到的最大电枢电流和获得最大电枢电流的初始条件,为永磁电机设计永磁体工作点的确定提供了理论依据。
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.
