大规模电力系统主振模的计算——λ型Schwartz矩阵的新性质及应用

A New Property of A-Schwartz Matrix and Its Application in Estimation for Main Oscillation Mode of Large Power Systems

在文献[1]中曾提出过一种大规模电力系统主振模计算的新算法。本文主要贡献是:给出了该新算法的理论依据:关于λ型Schwartz矩阵性质的一个新定理(本文定理3),然后讨论了这一定理应用于大规模电力系统主振模计算时的实际问题。

In this paper, a new theorem on the property of λ-Schwartz Matrix is established and proved. This theorem gives the theoretical foundation of the new algorithm for estimation of main oscillation mode in large power systems, which was proposed in[1]. Some practical problems on the applications of this theorem are also disccussed in the paper.
