Electric power system graph model maintenance anti-error method and system

The invention discloses an electric power system graph model maintenance anti-error method and system, and relates to the technical field of electric power system automation, and the method comprises the steps: carrying out the joint maintenance and case analysis of a graph model based on regional and network provincial power dispatching systems; performing data mining clustering analysis on typical graph model maintenance errors in the graph model of joint maintenance and case analysis; and system identification and blocking of anti-error features are carried out based on data mining clustering analysis, and alarm information is generated to carry out personnel automatic scheduling. According to the method, the system is allowed to synchronously update and maintain the graphic model through joint maintenance, resource sharing and information consistency are achieved, and the operation efficiency and reliability of a power grid are improved; typical errors in graph-model maintenance are analyzed by applying a
