摘要/Abstract

摘要： 电力系统保持小干扰稳定性是当前我国正在进行的大区联网运行的前提条件之一.在本文中采用多机系统的特征分析法,并应用电力系统分析综合程序（PSASP）对华北电网（含山东电网）和华中电网（含四川和重庆电网）的联网运行方式下的小干扰稳定性（侧重于低频振荡）进行了研究，分析了联网方式下存在的多个低频振荡模式,并对每个振荡模式做了模态分析,为下一步进行的电力系统稳定器的安装和配置提出了指导性的建议.

关键词: 低频振荡, 振荡模式, 振荡模态

Abstract: Smallsignal stability of power system is one of the preconditions for connecting large area electric power grids running in China. Based on the eigenanalysis method for multimachine electric power systems, the smallsignal stabilities (more emphases is given to lowfrequency oscillatory study) of the connected north China (including Shandong power network) and central China (including Sichuan and Chongqing power networks) power grids were studied using the Power System Analysis Software Package (PSASP). The analyses of oscillatory modeshapes for each lowfrequency oscillatory mode were put forward. The directional guidance was provided for installing and setting power system stabilizers.

Key words: oscillatory mode, oscillatory mode shape , lowfrequency oscillation
