为了提高大功率永磁风力发电机的运行可靠性，文章以额定功率1．5MW、78极324槽的直驱永磁风力发电机为例，阐述了两种直驱永磁风力发电机变流器拓扑结构的工作原理及特点，基于MATLAB/SIMULINK仿真技术，分析了直驱永磁风力发电机在缺相、变流器故障以及额定状态下的运行特点，通过仿真表明：采用容错技术，可使直驱永磁风力发电机在缺相、变流器故障时运行情况与正常运行情况基本相同，提高了电机在风力发电系统中的可靠性。

In order to raise the operation reliability of large power permanent magnet wind generator , the principle and characteristics of two types of converter topology for direct -driven PM generator with output power of 1.5MW, 78-pole number and 324-slot number is explained .Based on the MATLAB/SIMULINK, the operation performance of direct -driven PM generator is analyzed under the con-dition of losing-phase, converter fault and normal operation .The simulation results show that the normal operation of direct -driven PM generator direct -driven permanent magnet generator is the same as that of losing -phase and converter fault through fault -tolerant technology , this will greatly raise the operation reliability of direct -driven PM generation system .
