Research Of Substation Long-distance Video Surveillance System Based On IEC 61850 Protocol

Substation automatic communication system is developing fast with higher demands. Simultaneously, long-distance video surveillance system has to be adapted to provide more excellent services according to those requirements. Based on the function criterion of telecontrol and relay protection devices in IEC 61850 standard, information of video monitoring system controlling model is designed in this thesis. Firstly, we analyses system functions, configures logical nodes, devises UML models for data and services. Communications in this model depend on XML Schema, which realizes the interoperability between source database and XML documents. This process unifies all kinds of data types. Furthermore, we have implemented a network emulator for system configuration with SCL. Results indicate that this system model is designed reasonably showing strong concept of object-oriented. Besides, data and services supply self-description well. Generally, all the work may be taken for some reference to the fulfill project of video surveillance system based on IEC 61850 standard.
