A new method on general remote automatic bus transfer

At present, many 110 kV distribution stations adopt double loop series connection mode, which makes the present remote automatic bus transfer devices unapplicable. So the paper proposes a new general remote automatic bus transfer method based on the optical fiber communication. The distribution stations connected in series can exchange information with each other. The traditional bus based method is extended to the working line based method. If the working power is powered off for some reason, the nearest switch to the fault point will be switched off and the nearest switch to the power point will be switched on, so the system power supply will be recovered as far as possible. The method is simple, applicable and practical.
