摘要

将奇异值分析法（SingularValueDecomposition

SVD）和连续潮流算法（ContinuationPowerFlow

CPFLOW）相结合应用于电压静稳极限的分析预测

并针对四川电网 2 0 0 3年运行参数进行计算分析

得到了系统距离电压崩溃点程度的有效信息

并找出了系统的薄弱点和最灵敏控制方向

Abstract

Singular value decomposition method combined with continue power flow method has been applied to the analysis and prediction for voltage steady-state stability limit of Sichuan power grid in this paper. Calculation and analysis for operational parameter of Sichuan power grid in 2003 have been carried out

from which the effective information of voltage steady-state stability margin has been obtained and the weakness nodes and the most sensitive control direction have been found out as well.
