摘要
以2 MW、六相半直驱永磁风力发电机为例,阐述了多相电机相数的定义及其绕组结构,基于场路耦合法,构建了多相半直驱永磁风力发电机的有限元模型,分析了半直驱永磁风力发电机的动态性能及在缺相情况下的运行特性,在此基础上,对比了直驱与半直驱永磁风力发电机性能。仿真表明,采用该方法设计的多相半直驱永磁风力发电机是可行的,可靠性较高。
The definition of phase number and winding structure for half-direct driven permanent magnet generator with the 2 MW and six-phase were described in the pqper.Based on field-circuit coupled method,the finite element method model of multi-phase PM generator was built,and the operation performance of half-direct driven permanent magnet generator with the 2 MW and six-phase was studied under the condition of six-phase and losing phase.The direct-driven and half-direct-driven PM generator were comparatively analyzed.The simulation results show that the design method for the half-direct-driven permanent magnet wind generator is feasible and high reliability.
