[Abstract]:With the development of smart grid and the progress of network communication technology and substation automation technology, substation unattended substation has become the trend of intelligent substation construction. The linkage between video information and environmental quantity information, and the information interaction between integrated automation system and video surveillance system are the basis of realizing unattended substation, and the core of substation auxiliary monitoring system intelligence. However, at present, there are many kinds of communication protocols in substation auxiliary monitoring system, and the implementation of linkage has limitations. With the gradual expansion of power grid scale, the realization of linkage is becoming more and more complex. At present, there is a lack of effective methods to test the process and results of video linkage. Therefore, it is of great practical significance and practical application value to carry out the test research of the linkage between the auxiliary monitoring system and other subsystems. In this paper, event simulation and protocol simulation are adopted, according to the alarm event push mode of substation, based on IEC60870-5-104 telecontrol protocol, SIP protocol, event injection technology, XML analysis technology, network programming technology and so on, the video linkage test is realized by C programming language under the development platform of Visual Studio 2010. The main work is as follows: 1) the significance of linkage testing of auxiliary monitoring system in the construction of intelligent substation is analyzed. Based on the analysis of the linkage structure of the existing auxiliary monitoring system, the IEC60870-5-104 telecontrol protocol and Q/GDW 517.1 / 2010 "Power Network Video Surveillance system and Interface part 1: technical requirements", which are widely used in the linkage system, are studied. 2) aiming at the linkage scheme of the auxiliary system, the simulation and test method is put forward, and the techniques such as event injection and timing control are studied. The overall test architecture of linkage protocol test and linkage functional performance test is designed. 3) according to the simulation test method, on the basis of the research of linkage protocol, the interface test and fault tolerance test are used to start with the forward protocol interoperability test and the reverse protocol fault tolerance test, respectively. IEC60870-5-104 telecontrol protocol test and power network video surveillance system interface B linkage part protocol test are realized. 4) on the basis of protocol testing, the alarm event simulation library is established, and the alarm event trigger process is designed by using timing control method to realize analog event injection. Using XML analysis and other technologies to extract feedback message information, analyze linkage efficiency, linkage accuracy and other performance indicators to complete the linkage performance test. 5) through the joint test with equipment manufacturers, the correctness of the test method and the stability of the test system are verified. The realization of linkage testing has a good practical application value for the construction of unattended intelligent substation auxiliary monitoring system.
