Design And Implementation On Visual System Ofequipment Level In Smart Substation

Intelligent substation communication standard IEC61850 standard system is used, the information transmission device between the optical transmission of the electrical signals into digital signals by the conventional substation cable transmission is that the "see and feel" of the input sample values and connecting the output terminals of the trip, into a web-based transmission SV / GOOSE digital signals. Intelligent substation circuit between devices is no longer a pure signal circuit structure composed of a single cable transmission, but in fiber-based digital communications network structure, each fiber simultaneously transmit multiple signals from the outside can not be directly the physical connection to the analysis of the entire loop, instead it is a virtual circuit between the devices. By means of conventional MultiMate’s, testers and other tools to directly relay debugging and testing equipment layer cannot meet the needs of debugging and testing of intelligent substation.By analyzing the debugging and testing workflows intelligent substation equipment to IEC61850 standard based on consistency, developed a PC as the hardware platform, cross-platform, intelligent substation equipment with a graphical interface layer visualization system. GOOS signal transmission function of the system through multiple intelligent devices within the simulation of intelligent substation, mutual Subscribe visual display equipment between, SV signal transmission, and verify the correctness SV / GOOSE signal connections passed achieve Quartet in smart substation commissioning and testing process of "accurate, visualization, rapid" and can help design and engineering personnel intuitive and efficient for device interconnection relationship quickly locate, analyze and diagnose project implementation, operation and maintenance of the emerging complex problems, improve work efficiency and enhance the operational level and intelligent substation related professional and technical personnel to maintain the level of cost savings greatly.
