摘要
为了研究混合磁极式的混合励磁永磁同步发电机转子上既有永磁体、又有励磁绕组的运行性能,建立了混合磁极式的混合励磁永磁同步发电机的基本方程;根据该电机的转子结构及定子绕组的实际连接方式和空间分布情况,分析了模型中电感参数及永磁体在其他回路中产生的磁链的特点,并给出其表达式;采用有限元法计算各参数表达式中的系数,能准确考虑磁极形状及永磁体的作用,利用数值方法对该电机的性能进行仿真。在1台混合磁极式的混合励磁永磁同步发电机样机上进行了实验,仿真结果和实验结果吻合较好,验证了仿真模型的正确性和参数计算的准确性。
Hybrid excitation permanent magnet synchronous generator with hybrid poles has permanent magnet and field windings in the rotor.The basic equation of this electric machine was established in order to study its performance.According to the structure of the rotor and the actual connects and spatial distribution of the stator windings,the characteristics of the inductance paramerters and the flux of the other loop created by permannent magnet were analyzed,and the expressions were given.The coefficients of each parameter expression were calculated using the finite element method,which took into account the shape of the magent poles and permannent magnet,and the simulation of the machine performance was performed using numerical methods.Simulation and experiment results agree well with test results on a prototype,which verifies the correctness of the simulation model and the accuracy of parameters calculation.
