Research on the Total Solution for Relay Protection of the Wise Substation Based on Comprehensive Perception

Based on the comprehensive perception technology, this paper firstly proposes solutions of relay protection for the perception layer with the usage of the physical states, environment states and the multi-source fault information. Secondly, it clarifies the applicability of 5G wireless communication technology in relay protection devices for the network layer, and then it proposes the substation IoT management platform and the secondary data center platform for the platform layer. Finally, the paper proposes the “wise goals” of the wise substation for the application layer, which are wise display, wise decision-making and wise maintenance. With the research of the total solution for relay protection, the paper provides a reference for the development of relay protection technology.
