摘要
本文应用分叉理论研究电力系统临近电压失稳时的行为，推导出了参数变化致使系统失去电压稳定的判别定理，对电力系统电压稳定性机理作了尝试性研究。
This paper presents an analysis of power system voltage stability on the basis of the bifurcation theory, derives a discriminant theorem to distinguish the systemvoltage. stability following the changes parameters, and makes an attempt to study the mechanism of voltage inability.
