摘　　要：本文证明了严格的静态电压不稳定灵敏度判据 ,并对 d QL / d VL 和 d PL / d VL 电压稳定判据进行评析。In this paper, static voltage stability criterion is mathematically proved that is equivalent to the singularity analysis of a modified Jacobi matrix of load flow equation with considering load voltage characteristics. It is shown that the dQ L/dV L and dP L/dV L as voltage stability indices are not strict in general except keeping real and reactive load constant.
