In the context of the Internet of Things, it is necessary to perceive the surrounding environment, facilities, abnormal conditions, etc. of the substation, and through the Internet of Things, it is possible to quickly establish an automatic mode of identity distinction, state perception, data collection, etc., and through visualization , Automated and mobile relay protection, so as to comprehensively improve the intelligence and stability of relay protection. With the rapid construction and development of various modern information technologies, the application of information technology to substations and the construction of a multilateral collaborative intelligent monitoring system for substations based on the Internet of Things can promote the development of substation monitoring systems in a more intelligent and diversified direction. This article first briefly describes the architecture design of the multilateral collaborative intelligent monitoring system for substations, and proposes the future development direction to effectively promote the modernization and intelligent construction of substations.
