Research on Key Technologies of High Reliable Local Communication for Multi-Business Access in Power System

With the construction of new power systems, diversified power businesses have emerged with differentiated requirements on power communication technologies in aspects like bandwidth, direction, coverage, QoS and business security boundaries. Therefore, this paper conducts research on key technologies of highly reliable local communication for multi-business access in power systems, and designs a multi-modal intelligent fusion gateway that is compatible with various common communication protocols and dedicated power communication protocols. It verifies the performance and availability of the multi-modal intelligent gateway and its software system, effectively reducing the construction cost and network maintenance difficulty of terminal communication access networks and improving network adaptability.
