Research on Simulation Control and Implementation of Network-Based Dual CAN Communication for Ring Network Cabinet

At present, the role and influence of the power system on all walks of life in society is increasingly high, and the reliability of the power supply is particularly important, so to crack the problem of power outages caused by maintenance of the non-maintenance section and to achieve mutual supply of lines. In this paper, by establishing a distribution network based on the ring network structure, the use of the ring network cabinet equipment in the ring network operation mode load switch division and closure operation to achieve the purpose of transferring power supply. The use of network double CAN (controller area network) communication makes the same line non-stop without maintenance sections, ensuring the continuity of power supply, effectively improving power supply reliability and minimising the impact of power distribution equipment faults and maintenance outages. The traditional power change operation method is carried out by manual hand cranking of the load switch, with a high risk factor for the operation of powered rotating operations and great safety hazards for the operator, which has not fully adapted to the needs of modern grid construction and development. This paper deals with a ring switch tool that can automatically close and close load switches, which can effectively reduce labour intensity, protect personal safety and ensure safe and stable operation of the power grid.
