摘　　要：以基于TSMC的永磁直驱型风力发电系统为研究对象,建立TSMC并网逆变级的数学模型,提出TSMC直驱型风力发电系统的集成控制策略,将最大风能跟踪、输出功率调节、变速恒频控制通过网侧逆变级的集成控制实现,且无需进行稳定直流电压的功率平衡控制,系统控制复杂度降低。仿真结果验证了该控制策略的有效性。The control strategy of permanent magnet direct-drive wind turbine was investigated based on two-stage matrix converter（TSMC） in this paper. The model of grid-connected inverter-stage was developed, a novel intergrated control strategy of TSMC permanent magnet direct-drive wind turbine was proposed, in which the maximum wind energy tracking, output power control and variable speed constant frequency （VSCF） were realized by intergrated control at the inverter-stage, and there was no need of power-balancing control strategy to decrease the dc-bus voltage fluctuation, which reduced the control complexity. Simulation results verify the validity of the proposed control strategy.
