摘要
电力网络中存在某些脆弱环节,对电力系统的稳定性有着重要的影响。本文将特征结构方法与电流注入型相结合,推导出一种判断电力系统薄弱节点,薄弱线路的方法。该方法利用电流注入型与电力系统的网络结构相对应,进而评定实际电力网络结构稳定性的强弱。
Some weak links in grid will affect the stability of power system. An algorithm which combined eigenvalue structure analysis（ESA） with current-influx model and gave the information about weak nodes and lines in grid was presented. Based on current-influx model which corresponded to grid, this algorithm was decisive for grid stability and pointed out the week point in grid.
