摘要 介绍了3 MW/3 kV直驱式风力发电并网变流器的设计。详细论述了主回路参数设计、IGBT并联技术、变流器控制方案。所设计的变流器主电路采用三电平拓扑加LCL滤波器的结构;控制系统使用双DSP控制,机侧和网侧分别采用基于扩展反电势估算的无传感器矢量控制和电网电压定向矢量控制。最后通过实验验证了所设计变流器的有效性。 This paper introduces a 3 MW/3 kV direct-drive wind power grid-connected converter design.The designs of main circuit parameter,IGBT parallel technology,converter control strategy are discussed.Converter use a lot of tech- nology to meet the design requirements such as three-level topology,LCL filter,double DSP control.Sensorless vector control based on extended back-EMF estimation and power system voltage oriented vector control.Finally,this paper verifies the effectiveness of design converter through experiments.
