摘　　要：通过分析双馈风电机组异常电压情况下的可控范围,得出电流和调制度限制是影响双馈风电机组高低电压耐受能力的主要因素,在直流母线加装超级电容储能系统可改善直流母线暂态性能,通过与网侧变流器协调控制,可有效提升异常电压耐受能力,扩大机组运行范围。The controllable area of DFWT system under abnormal grid voltage was analyzed and it was concluded that limitation of current and modulation are the key factors affectingits operation area. Installation of super-capacitor interfaced with a DC-DC converter is beneficial to suppress DC bus transients and with combined control with grid-side converter abnormal voltage tolerance of DFWT is largely enhanced.
