| 摘 要： | 传统的电压稳定测度指标都把潮流方程邪念可比矩阵奇异点作为系统电压失稳的临界点,而不考虑系统发生Ｈｏｐｆ分叉的可能性,因而上应的测度指标不可避免地具有一定的冒进性。

| Abstract: | Almost all proximity indictors of traditional power system voltage stability treat voltage stability critical point as the saddle node bifurcation point, while the Hopf bifurcation point is paid no attention to. Therefore, they are somehow optimistic in applications. In this paper, based on the modified Jacobian matrix model, an indictor in frequency domain is presented. It can be used to measure the proximity to voltage instability which is indicated by either Hopf or saddle node bifurcation. The results of two example power systems show that the proposed indictor can approach nearly "linearly" to zero in a wide interval around the system critical point. |
