摘要
本文揭示了电力系统暂态电压最大跌落与暂态势能之间的联系,指出电压最大跌落发生在临界的等值二机平面上暂态势能到达最大的时刻。文中还提出了用EEAC法进行暂态电压最大跌落的分析方法。对浙江电网的仿真结果表明,利用EEAC分析首摆电压最大跌落具有快速和较为准确的优点。
Utilities are concerned very much with post-fault transient voltage dips.Assumptions used by some energy-based criteria for voltage dip analysis arediscussed.It is proved in this paper that the maximumvoltage dip will occur at the point where the correctedpotential energy on the OMIB mapping reaches itsmaximum. The voltage dip analysis with EEAC hasbeen implemented and good results are obtained.
