埃及变电站二次设计特点分析及启示

Analysis and Revelation of Substation Secondary Design in Egypt

依托南京南瑞继保电气有限公司实施的多个埃及变电站工程,分析整理埃及电网在二次回路、高压线路、主变、母线以及中压馈线保护方面的主要技术特点,同时与国内技术特点比对,对国内承接埃及二次设计工作提出了一些建议,为今后中国电力企业在埃及的电网项目建设提供重要技术参考。

This paper is based on several Egyptian substation projects implemented by Nanjing NR Electric Co.,Ltd.,to analyze and sort out the main technical characteristics of Egyptian power grid in the protection of secondary circuit,high-voltage line,main transformer,bus and medium-voltage feeder.Then,the paper makes comparison with domestic technical characteristics,and finally puts forward some suggestions for China to undertake the secondary design work in Egypt,which provides important technical reference for the future construction of power grid projects in Egypt by Chinese power enterprises.
