摘要
探讨了时滞环节对电力系统小扰动稳定域的影响。首先推导了微分一代数方程在考虑时滞影响时的小扰动稳定分析方法;进一步给出一种基于双层优化的追踪算法,用于求解含时滞环节的电力系统小扰动稳定域的边界;最后,利用该算法和2个典型系统,深入探讨了时滞环节对小扰动稳定域边界及构成性质的影响。
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.
