In order to improve the adaptability and performance of automatic bus transfer equipment, a method of automatic bus transfer based on substation area information is proposed according to the technical features of intelligent substation. Based on basic configuration unit of automatic bus transfer and its information configuration and reasonable combination, the automatic bus transfer equipment can meet the application requirements under various connection modes. Through using branch switch state information and current information, the operation mode of substation can be identified online. According to the result of online identification, the automatic bus transfer function is adjusted to improve the adaptability. In addition, the coordination between different automatic bus transfer and the performance of automatic bus transfer device can be improved by using the technical advantages of substation information sharing. The correctness of the method is verified by digital simulation.
