Abstract

Power system small signal stability region considering time delay is tentatively investigated in this paper. Stability analysis of the differential-algebraic equation is first briefly reviewed. Then a two-layer optimal-based algorithm is given to trace the power system small signal stability region with time delay considered. Two simple power systems are analyzed by the method proposed and it is found that time delay has significant influence to the boundary of the small signal stability region. So it should be carefully considered in small signal stability studies.

考虑时滞的电力系统小信号稳定域

本文对考虑时滞的电力系统小信号稳定域进行了初步研究。首先简要回顾了微分代数方程的稳定性分析。在此基础上，提出了一种考虑时滞的两层优化算法来跟踪电力系统小信号稳定区域。用该方法对两个简单的电力系统进行了分析，发现时滞对小信号稳定区边界有显著影响。因此在小信号稳定性研究中应慎重考虑。
