摘　　要：将双级矩阵变换器(TSMC)应用于变速恒频(VSCF)风力发电系统。该系统采用TSMC作为双馈发电机的交流励磁电源,利用定子磁场定向的矢量变换控制实现发电系统有功功率和无功功率的独立调节;并采用最大风能捕捉策略,实现不同风速下跟踪最大风能曲线,实现风能的有效利用。仿真结果表明该系统具有良好的稳、动态变速恒频运行特性,输出可以实现有功、无功功率的独立调节,且输出电能质量高。验证了所提控制方案的正确性和有效性。This article explored how to use two-stage matrix converter（TSMC） in variable-speed constant-frequency （VSCF） wind power generation system. Excited by TSMC, the system permits active and reactive power regulating inde- pendently by applying stator flux oriented vector control and enables the generator capturing maximum energy from wind by tracking optimal wind curve. The good performance of the system obtained from simulation. The system has a good stable and dynamic VSCF operation, and it can independently control the active and reactive power, and the output has a high quality. It demonstrates the correctness and availability of the scheme presented.
