[Abstract]:With the development of Internet of things technology, the integration of human society and physical system has been realized. The technology of Internet of things is applied to the intelligent substation, which integrates the functions of video surveillance, safety guard, fire alarm, heating and ventilation and so on. It can realize the remote monitoring of the personnel on duty and improve the monitoring quality of the substation. On the basis of introducing the background and significance of the research, analyzing the status quo of the intelligent substation auxiliary system and the current situation of the Internet of things technology, combined with the construction of the 220kV Xijing intelligent substation, the paper deeply studies the technology of the Internet of things in the substation management. Control, operation, maintenance and other applications. In this paper, the related concepts of intelligent substation and Internet of things are introduced, the relationship between the technology of Internet of things and smart grid technology is analyzed, and the application prospect of Internet of things in intelligent substation is analyzed, which provides the theoretical basis for the following research. Then, the information collection and transmission mode of Xijing substation sensor network, the transmission mode and low-power technology of wireless sensor network in Xijing substation are studied, and the networking mode of Xijing transformer sensor network is deeply studied. Then, the advantages of cooperative perception and multi-source heterogeneous information fusion are introduced, and the cooperative sensing strategy and information fusion strategy are deeply studied. The cooperative perception and information fusion between image sensor and other sensors are analyzed with alarm information as an example. Then, the intelligent management and control software of the auxiliary system of Xijing substation is developed, the subsystems of the auxiliary system are integrated, the communication protocol of the auxiliary system is studied, and the technical and functional characteristics of the system are explained. Finally, the field test and verification of Xijing transformer are done, including electromagnetic compatibility test, electromagnetic environment test, sensor performance test, software function test and electrical performance test. The results show that the Internet of things technology can meet the needs of automatic control, intelligent regulation and coordination of the auxiliary production system in 220kV Xijing Substation, and has opened up a new field of application of Internet of things technology in intelligent substation.
