基于GOOSE的变电站保护功能应用研究与实现

Research and Implementation of GOOSE based Substation Protection Functions

分析了GOOSE通信在变电站保护功能中的应用。文章主要探讨了GOOSE在失灵保护、重合闸、分散式方向母线保护等保护中的应用原理和信号需求情况,给出了相关的GOOSE信号交互表和动作逻辑。另外文章还分析总结了GOOSE保护应用的各种网络结构的性能,对于不同的电压等级,推荐了合适的网络结构。最后,还指出了保护装置中GOOSE功能实现应采取的一些可靠性措施。

This paper discussed the GOOSE application in substation protection functions.Based on the research of the GOOSE communication mechanism and related signal exchange requirements in several protection functions such as circuit breaker failure,auto re-close and distributed directional bus protection,the author proposed the GOOSE publish/subscribe signal table for related functions,as well as their operation logics.In addition,the performance of several kinds of real-time GOOSE application oriented network structures have been analyzed with suggested solutions for different substation levels.Finally,some technical methods for protection device have also been put forward to improve the GOOSE communication reliability in substation.
