[Abstract]:In order to meet the needs of the construction and development of intelligent substation, it is necessary to develop a simulation test system for testing, evaluation and testing. The function and performance of intelligent electronic devices or intelligent components can be tested as a whole. A controller hardware circuit of intelligent substation distribution test system based on wireless communication technology is developed. According to the technical characteristics of intelligent substation, this paper puts forward the concept of distributed testing system for secondary equipment of intelligent substation based on the existing digital test device, and gives the test method and flow chart. A new type of intelligent substation testing device is developed. The WIFI wireless LAN technology is integrated into the intelligent substation distribution test system, and the communication between computer and controller is realized. The wireless communication technology is used to make the position of the system controller and the test convenient and flexible. Based on the intelligent substation distribution test system, The technical route, working principle and composition of distributed test system are studied, and the application of wireless communication in intelligent substation distributed test system is analyzed. The hardware design and implementation method of wireless function module based on WIFI are studied in detail. Finally, the application of distributed test system is expounded by taking 220KV intelligent substation as an example through the detailed analysis of the work flow of distributed test system. The experimental results show that the distributed test system based on wireless communication technology can test the technical performance of substation secondary system completely, and can also support joint debugging between intelligent substations. It provides a new technical means for intelligent substation field test.
