The invention discloses a G-language-based generating method of an intelligent electronic equipment electric wiring graph. The method includes: hierarchically saving the electric wiring graph to a G file according to a G language hierarchical structure; by intelligent electronic equipment, analyzing the G file, and reconstructing the association of the graphic information and dynamic data of the electric wiring graph; by the intelligent electronic equipment, drawing the static graph and dynamic graph of the electric wiring graph on a liquid crystal screen; by the intelligent electronic equipment, inquiring and comparing the dynamic data of the electric wiring graph, and completing the dynamic graph refreshing of the electric wiring graph; by the intelligent electronic equipment, inquiring the sensitive areas of the electric wiring graph, and issuing a control command to achieve the control function of an electric element. By the method, the electric wiring graph is displayed on the intelligent electronic equipment, a graph description file is simplified, the operation state and real-time tidal information of an intelligent substation can be dynamically displayed in real time, a visualized electric element control manner is provided, and the intelligent substation is allowed to operate safely and stably.
