At present, it is necessary to effectively perform a secondary design during the operation of 110 kV substations in order to improve the level of operation of the power system. The main devices are automatic power supply switching devices, automatic reclosing and voltage regulating switches with load regulation used in the secondary design process. It is necessary to carry out the necessary protective measures for the circuit, the handling of short-circuit faults, the design of the main transformer protection system and line protection, etc., to be optimized and combined with the actual geographical conditions, the operation of 110 kV substations to achieve the design goals.
