摘要
本文以安哥拉地区维安娜(Viana)400 kV变电站、莫罗本托(Morro Bento)220 kV变电站和本奇苏(Bom Jesus)60 kV变电站为例,介绍了安哥拉变电工程保护及电气二次设计在主接线、备用电源自投、防误闭锁、保护跳闸回路等方面与国内变电站的设计差异,并对不同方案的优缺点进行了分析。
This article takes Viana 400 kV substation, Morro Bento 220 kV substation,Bom Jesus 60 kV substation in Angola as an example,introduced the design difierences of electrical protection and secondary design engineering in electrical main wiring, automatic standby power input, anti misoperation locking ,protection,trip circuit and other aspects from the domestic substation, and analyzed the the advantages and disadvantages of difierent scheme.
