变电站数字化改造中GOOSE代理机的实现

随着以变电站通信网络和系统标准IEC61850为基础的数字化变电站的应用,出现了越来越多的变电站数字化改造项目。在变电站综合自动化系统中,测控设备通常用逻辑联闭锁的方法来加强一次设备操作的安全性与可靠性,常规变电站装置之间的联锁信息基于IEC103信息模型,而在数字化变电站中采用全新的通用面向对象的变电站事件（GOOSE）作为联锁信息的交换机制。以高性能IXP425网络处理器和X86通用处理器构造双处理器系统,并以VxWorks实时操作系统为基础,采用组件化的软件设计思想,实现了一种实时嵌入式GOOSE代理机。该装置可用来桥接新老自动化系统的间隔层,完成设备之间联锁信息的交换,满足目前变电站改造中新旧系统安全、平滑过渡的应用需求。

Realization of GOOSE Proxy in Substation Digitized Reconstruction

With the application of digitized substation based on Communication Networks and Systems in Substation IEC61850,more and more projects about substation digitized reconstruction have come out.In the substation automation system,the devices strengthen safety and liability of the primary device operation through the method of interlock.In normal substation the interlock information is based on the model of IEC103,while in digitized substation,the GOOSE is adopted as exchanged mechanism of the interlock information.
