中文摘要:

针对风电系统在受电网扰动或故障时突然脱网给系统造成的严重影响,提出了利用超级电容器提高风电机组的故障穿越能力的控制方法。在分析超级电容器、双馈感应电机和变换器模型的基础上,建立了基于超级电容器的故障穿越控制器模型,提出了相应的控制策略,并对基于超级电容器的多机并网系统进行了仿真分析。仿真结果表明,在网侧并联超级电容器使故障时的转子电流降低,母线电压提高,从而提高了双馈感应电机的故障穿越能力。

英文摘要:

To avoid serious influence caused by wind turbine suddenly loss connection from the power system when power grid disturbance or fault happened, a kind of control method using the super capacitor to improve the fault ride through (FRT) of wind turbine is proposed. Based on the analysis of Super Capacitor (SC), Doubly fed induction Generator (DFIG), and converter models, the FRT system controller model Based on SC is built. Multi-machine parallel connection SC system is simulated. Simulation results show rotor current is reduced and bus voltage is increased for installation SC, thus FRT ability of DFIG is improved.
