摘要
根据潮流方程的多解性和分歧现象，将启发式能量函数法引入电力系统电压稳定性分析，从能量的角度对电压稳定进行诠释，提出了考虑能量对负荷灵敏度分析的△Ｖ＿ｍ判据，提高了判别准确度，为系统中电压稳定薄弱区域的识别和不同规模系统间电压静态稳定性的比较提供了良好的依据。
According to multisolution of power flow equation the hearistic energy function method is introduced to voltage stability study of power systems. A △V_m criterion in which the sensitivity of energy to loadvariation considered is presented, and more accurate results have been got.
