摘要
本文针对兆瓦级的永磁直驱同步风电机组(D-PMSG)多运行于并网发电状态,在DIg SILENT/Power Factory仿真软件中搭建了基于双PWM全功率变流器的D-PMSG并网仿真模型;阐述了系统的运行原理,对机侧和网侧的变流器的控制策略进行了详细的分析,该系统能够实现风能最大功率追踪以及并网控制,仿真结果验证了所建模型的正确性和控制策略的可行性。
According to the operation characteristics of permanent magnet synchronous direct-drive wind turbines for megawatt（D-PMSG） to run in grid-connected power generation, the model of PMSG wind power system is built on DIgSILENT/PowerFaetory platform. The wind power system control strategy of generator-side converter and grid-side converter are analyzed in detail. The simulation results show that the system can achieve maximum power tracking and grid control, meanwhile verify the validity of the model and the feasibility of the control strategies.
