The utility model relates to a standby automatic switching series supply substation for remote logic transmission between stations, including a substation, a standby automatic switching device and an optical fiber. The substation comprises a main power supply input line, a main power supply, an incoming switch, a standby switching switch, a standby incoming line switch, a first bus and a second bus, and the two standby automatic switching devices are changed by optical fiber. Power station automatic switching communication, substation main power supply into the main power supply connected to the main power supply and then through the input switch with the standby switch, standby switch into the line for electrical connection. The standby automatic switching device of the remote logic between stations of the utility model can be put into operation by the standby automatic switching device of the optical fiber direct communication, and the 110 kV standby automatic switching device of the two series substations can be put into operation. When the main power supply of the substation is faulty, the switch of the fault line will be jumped off, and the switch will be lost through the channel at the same time. The information is sent to another substation and automatically switched on and off to the standby power supply to ensure the reliability of the system power supply, which has a great positive impact on the society and has a high popularization value.
