Exploration and research of smart substation secondary system simulation testing and integration testing new mode

At present, it has large amount of work in environment building, many coordination links, and long debugging period, and the problem that the advanced functions are difficult to make integrated debugging in the whole system in the secondary system test and integration test of smart substation. Aiming to that, this paper puts forward a new mode of intelligent substation secondary system simulation test and integration debugging test. It takes application function test and integration debugging of intelligent substation as the center and separates the integrated test of secondary system effectively. By means of equivalent simulation and simulation test, the simulation test system is constructed to support the application function test and integrated debugging, which not only effectively improves the efficiency of each application function integration debugging of intelligent substation secondary system, but also achieves the same debugging effects as using integrated debugging mode of integrating real device. In order to realize the new pattern, the traffic sniffer technology of station control layer application and the universal simulation technology of spacer layer secondary device are introduced. The model has been applied in smart substation factory integrated test, field integrated debugging and intelligent substation expansion debugging, and achieved good results, which has good economic benefit and social benefit.
