A visualized power supply scheme auxiliary compilation method based on a power grid GIS (Gas Insulated Switchgear) is disclosed. The method comprises the steps of: step (1) positioning a reported installation address; step (2) searching power supply point equipment; (3) calculating an openable load; step (4) searching accessible equipment; and step (5) generating a power supply scheme. The method has the advantages that the power supply scheme auxiliary compilation function based on the GIS effectively improves the standardization and rationality of power supply scheme compilation and improves the working efficiency. The power supply scheme is displayed in a visualized mode, so that effective guidance on scene investigators is realized, the scene investigation time and the fault clearance time are shortened, and the satisfaction degree of consumers is increased. The visualized display of the power supply scheme is the specific application of client fault intelligent management technology and intelligent business expansion technology.
