研究了双馈感应发电机(DFIG)组通过高压直流输电(HVDC)系统接入电网的启动控制策略。系统建立了用于风电场接入的基于模块化多电平换流器(MMC)的直流输电系统的启动充电控制策略及双馈风机无冲击并入HVDC换流器的启动控制策略。仿真与实验表明系统可成功实现无冲击启动并正常进入额定工况稳态运行。
This paper discusses the starting-up strategy of integrating doubly-fed induction generator(DFIG) based wind farm through high voltage direct current(HVDC) system.The starting-up charging control strategy of modular multilevel converter(MMC) HVDC used in wind farm integration and it of DFIG's non-impact integration in HVDC converter are proposed.The simulation and experimental results show that the system can successfully achieve non-impact start-up and normally enter the stable operating status of rated condition.
