Technical framework and architecture of Beidou-3 smart grid converged networking

BeiDou-3 (BD3) navigation satellite system converged smart grid communication can effectively solve the problems of poor network interconnection, limited coverage, and poor flexibility of data access in the current power communication system, and has broad application space in ensuring data transmission reliability, positioning and search, precise timing, and operation inspection. This paper combines the BD3 precise space-time technology with various communication modes in the ground-based communication network of the power system to construct a BD3 smart grid converged networking framework. The framework combines various communication methods with internet of things (IoT) devices in the power system to form a system that can achieve state prediction, fault diagnosis, and location search functions. The proposed networking framework has reference value in the practical application of smart grid.
