【摘要】：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。
[Abstract]:The startup control strategy of doubly-fed induction generator (DFIG) connected to power network through HVDC (HVDC) system is studied. The start-up charging control strategy of DC transmission system based on modular multilevel converter (MMC) for wind farm access and the start-up control strategy of doubly-fed fan incorporating HVDC converter without impact are established. The simulation and experiments show that the system can be successfully started without impact and can normally enter the rated state of steady operation.
