Abstract :
Remote Video Surveillance System for Substation(RVSS) can supply real-time image of equipment in power system substation, improve the reliability and security of substation operation. RVSS has already become the necessary item of the substation construction. 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. In this paper, a method is introduced to realize linkage control of RVSS with relay protection. The information of protection action is obtained by analysis of the GOOSE message in substation communication network and the video system is then driven. Information security and protection are also researched. The scheme of the linkage control will carry into execution in the first digital substation in JiangXi province of China soon.
