[Abstract]:With the application of IEC61850 standard in intelligent substation, digital communication network, which can carry mass data, has replaced the traditional cable connection mode. The mode of information transmission between devices is changed from electrical signal transmitted by cable in conventional substation to digital signal transmitted by optical fiber. The original "visible, tangible" sampling value input and tripping output terminal are connected. It turns into a SV/GOOSE(sample value/Generic Object Oriented Substation Events) digital signal based on network transmission. The circuit between devices in intelligent substation is no longer a pure circuit structure composed of a single signal transmitted by cable, but a networked structure based on optical fiber digital communication, in which multiple SV/GOOSE signals are transmitted simultaneously in each optical fiber. It is no longer possible to analyze the entire loop from a direct external physical connection, instead of a virtual loop between devices. Traditional tools, such as multimeter and relay protection tester, can not meet the needs of intelligent substation debugging and testing. Based on the analysis of the debugging and testing work flow of intelligent substation equipment and based on the consistency of IEC61850 standard, this paper develops a visual system of intelligent substation equipment layer based on PC as hardware platform and cross-platform with graphical interface. By simulating the functions of several intelligent devices in intelligent substation, the system visualizes the transmission of SV signals by GOOS signals subscribed to each other between the devices, and verifies the correctness of SV/GOOSE signal connection transmission. To realize the "accurate, visual and fast" in the debugging and testing process of intelligent substation by Sifang Company, which can help design and engineer to see clearly the interconnection relationship of the whole station equipment. It is easy to analyze and diagnose the complex problems in the implementation and maintenance of the project, improve the working efficiency and save the cost greatly by improving the debugging and testing efficiency of the whole station equipment.
