The invention discloses a bus conversion method and a bus conversion device for maintaining the source end of a power system; the method comprises the following steps that a connecting point object in a transformer substation description system based on an IEC 61850 standard is expanded, and a type description parameter is added for the connecting point object; a scheduling main station end identifies the type description parameter of the connecting point object; and when the type description parameter is judged to be a bus, bus equipment is created. After the invention is adopted, the connecting point object can be expanded based on the IEC 61850 standard, the bus can be identified on the premise that no bus interval and other external new concepts are introduced, so that the sharing and the maintenance of bus information which is converted from an intelligent transformer substation to a main station are realized conveniently.
