The automatic transfer switching device is an effective technical means to enhance the reliability of power supply in the main grid.Addressing the issues associated with traditional automatic transfer switching devices in hand-in-hand grid structures,a novel intelligent remote automatic transfer switching scheme is proposed.This paper analyzes the principles of remote automatic transfer switching and elaborates on the implementation methods of the proposed scheme.An real-time digital simulator(RTDS)simulation test environment is set up to verify the implementation method,and the test results are presented.Ultimately,it is concluded that this remote automatic transfer switching scheme enables panoramic data perception between adjacent substations,resolves the issue of total voltage loss at a substation during faults in neighboring substations,and significantly improves the reliability of power supply in the grid.
