| 摘 要： | 建立了1 MW直驱风力发电系统电磁暂态仿真模型,在PSCAD/EMTDC环境下采用电压空间矢量脉冲宽度调制技术(SVPWM)真实地反映变流器的动态开关过程和谐波特性,实现了直驱风力发电系统的机侧最大风能跟踪以及永磁发电机定子电流的解耦控制和网侧直流母线电压稳定的控制。文章还对网侧变流器的软件锁相环(SPLL)进行了优化设计,使之能够快速、准确地跟踪电网基波正序电压,有助于改善网侧变流器在电网不对称故障期间的动态控制性能。

| Abstract: | This article establishes the SVPWM simulation model and describes the implementation method of SVPWM technique in PSCAD/EMTDC in order to truly reflect the process of the dynamic switching and the harmonic characteristics of the converter.In this article it also achieves the functions of the maximum power tracking strategy(MPPT),permanent magnet generator stator current tracking,decoupling control and network-side DC bus voltage stability control.Meanwhile,it improves the software phase-locked loop(SPLL) of... |
