摘　　要：以基于双级矩阵变换器(TSMC)的永磁同步风力发电系统为研究对象,阐述了最大风能追踪的原理,分析了TSMC直驱式风力发电系统的功率集成控制,提出了一种利用转子转动惯量功率实现最大风能追踪的控制算法。在传统功率控制算法中加入一个比例控制器,加快了系统捕获风能的速度。在Matlab中搭建了TSMC风力发电系统的仿真模型,仿真结果表明:新MPPT算法在风速突变时,加快了系统的动态响应;在风速不变时,保持系统的稳定运行,使系统能快速且准确地捕获风能。The control strategy of the permanent magnet synchronous wind power generation system based on two stage matrix converter（TSMC） was investigated. The power integration control of TSMC direct drive wind power system was explained. A new MPPT algorithm which takes advantage of rotor inertia power was proposed. A proportional controller was added into the traditional power control algorithm to improve the fast performance of the MPPT control. The simulation results show the new MPPT algorithm speeds up the dynamic response when the wind speed changes and maintains the stability when the wind speed keeps constant.
