摘　　要：计算了含双馈风机电力系统的动态安全域,并通过时域仿真对其边界的准确性进行了验证。经过大量仿真发现,在工程关心的范围内,接入双馈风机后,注入功率空间上电力系统动态安全域的边界仍可以用超平面进行拟合;分析了双馈风机接入对电力系统动态安全域的影响,发现双馈风机接入后引起动态安全域的外扩,并对其机理进行了探讨。The dynamic security region of power systems with double fed induction generator is calculated in the paper and the accuracy of the security region boundary is verified through time domain simulations. Extensive simulation results show that, within the acceptable range of engineering applications, the boundary of the dynamic security region of power systems with double fed induction generators can still be approximated by the hyper-plane（s） in the power injection space. The impact of the integration of double fed induction generators on the dynamic security region of power systems is also analyzed. It is found that the dynamic security region of power systems is enlarged with the integration of double fed induction generators. Furthermore, the mechanism of the change of the dynamic security region is studied.
