摘要
本文在分析电力系统两种经典静态等值法(Ward等值法与REI等值法)优缺点基础上,提出了在线Ward/REI等值法,其要点是在基态情况下对外网进行Ward等值,在实时情况下用REI等值法对等值网进行修正,最后给出两实验系统加以验证。
This thesis reviews the principles and main methods for steady state equivalents and presents Ward/REI method. Ward/REI method solves the boundary bus designation problem and gives reliable and accurate results. The method has been verified by simulation on the IEEE-30 buses and the East of China test system
