500kV变电站微机监控保护下放模式的设计

Design of Microcomputer Monitor and Protection Down-Model at 500 kV Substations

文章从工程设计的角度出发 ,结合已投运益阳变的具体情况 ,介绍了益阳 5 0 0kV变电站微机监控系统的结构及功能 ,保护下放所特有的抗电磁干扰、屏柜贴墙布置、故障录波光纤组网等设计特点和在国内首次采用的一些设计处理方法。总结了工程实践中的经验教训 。

From the view point of engineering design and in combination with the concrete situation of the Yiyang substation which has been put into operation, the paper has introduced the design characters including the structures and functions,anti-interference of electromagnet specially provided by the protection down, arrangement of the panels and cabinets against wall,emergent oscillographic optical fiber net composition,etc.of the nicrocomputer monitor system at Yiyang 500 kV substation and some design way firstly used domestically.The paper also has summed up the experiences and lessons in the course of engineering practice,inquired into some problems and given some comments.
