Abstract：Busbar automatic transfer switch (BATS) is an important equipment to guarantee the reliability of the electric power supply system, in a 220kV substation, if a 110kV bus is out of power, if there are BATS in the substation, then the strategy goal is to restore power by stopping the current transformer and using another main transformer power supply. But if the main transformers of the substation are all in voltage lost, the strategy will not be valid. The system which is proposed in this paper, according to the characteristics of regional power grid, considering the BATS's timing, telemetry and remote signals, and bus restoration process managed by restoration unit, automatic detect blocking conditions, charging conditions, startting conditions and operation conditions and the states of main transformer 220kV and 110kV buses, search standby power, then the power restoration strategy can be given. After the bus power is restored, automatic detect limit of power supply path, the load shedding strategy can be given or not. Experimental results showed that the system had achieved the desired purpose.
