基于IEC61850标准数字化与传统继电保护的比较

Comparison between standard digital on the IEC61850 and traditional protective relay

基于IEC61850国际标准通讯规约的500kV数字化变电站,采用了GOOSE跳闸技术和户外布置的智能终端装置,引起了继电保护实现方式上的变革。从工程设计与实施、状态检修实施、程序化操作、智能终端装置、500kV保护装置、主变保护装置、220kV保护装置等方面,对500kV数字化变电站与传统500kV变电站进行分析比较,浅谈两者的区别,使广大继电保护专业技术人员更快、更好地了解新技术。

Zhiyan, Jinhua, Zhejiang 500 kV power transmission project is the first digital substation adopted the international standard communication protocol-IEC61850 in our cotmtry. And it is the experimental and exemplary project of 500kV digital substation in the State Grid Corporation, in which the technology of tripping by the GOOSE network is used for the first time. The paper preliminarily discusses the dissimilarity of protective relay between 500kV Zhiyan digital substation and traditional substations, by comparing this substation with traditional one on the aspects of designing, implementing, state checking and repairing, procedure operation, intellect terminals and protection devices etc.
