摘　　要：本文以某3.6 MW永磁半直驱风力发电机作为研究对象,基于有限元法对两相及三相短路故障状态下半直驱风力发电机的短路电流进行了仿真模拟。以故障状态下风机去磁电流的最大值作为参考基准,并基于相同的去磁电流作用,比较永磁电机中两款不同属性的永磁材料的抗去磁特性。最终讨论永磁体材料属性对电机抗去磁性能的影响。Taking the 3.6 MW semi-direct drive wind generator as a research object,the short-circuit currents of the generator under two-phase and three-phase short-circuit fault states are simulated using FEM method.The anti-demagnetization performances of two different permanent magnet materials in the fan are compared under the same large demagnetization current,and based on the value of the maximum fault demagnetization current.Finally,the influence of permanent magnet material property on the anti-demagnetization ability of the motor is discussed.
