与GOOSE联动的数字化变电站遥视系统

面向通用对象的变电站事件(GOOSE)用于一次设备的操控及二次设备间的闭锁与联动,是数字化变电站中最重要的通信应用。如果变电站遥视系统(RVSS)能够捕获并解析GOOSE报文,它将能根据GOOSE信息实施与变电站自动化系统的联动。提出了通过中间件或通信服务器实现RVSS与GOOSE联动的2套方案,并对方案中的关键技术(映射关系的建立、GOOSE报文的捕获、GOOSE报文的解析和信息安全防护等)进行了研究。

Remote video system of digital substation supporting linkage with GOOSE

As the most important communication service in digital substation,GOOSE(Generic Object Oriented Substation Event)is used in the control of primary devices and the interlock and linkage among secondary devices.If RVSS(Remote Video System for substation)can capture and analyze GOOSE messages,the linkage between RVSS and substation automation system could be implemented.This function will promote integration of secondary systems and automation functions in digital substation. Two schemes using middleware or communication server are proposed and the key technologies of mapping relation establishment,GOOSE message capture and analysis,and information security and protection are researched.
