Method and system for realizing troubleshooting simulation of secondary circuit simulated fault in electric power system

The invention relates to the technical field of simulation, particularly to a method and system for realizing troubleshooting simulation of a secondary circuit simulated fault in an electric power system. At present, a method for realizing troubleshooting simulation of a secondary circuit simulated fault in an electric power system adopts real equipment, is high in cost and is low in training efficiency. The method includes the following steps: building a secondary circuit fault model system; a setting a troubleshooting task, and setting at least one secondary circuit fault in the secondary circuit fault model system; calculating by a simulation system according to primary system load flow data and a topological relation in a secondary circuit, so as to provide a corresponding protection action signal on a simulation equipment disc table; and performing electrified coloring on the related circuit in a secondary circuit diagram according to the at least one secondary circuit fault, so that a student can analyz
