The Study Of Intelligent Graphic Compilation Method For Grid Maintenance Scheduling

With the development of the Smart Grid, as the nerve center of Smart Grid, intelligent dispatching has excellent features of information-based, automation and interaction. Moreover, as one of the grid dispatching researches, how to make the grid maintenance scheduling be intelligent and interactive is an important subject. Currently, grid maintenance scheduling is not enough on the normative data, and the relevance between graphic display and intelligent analysis is not strong. To solve the problem, this paper proposes a novel analysis and compilation method for grid maintenance scheduling using graphic operation. The graphic operation platform is designed according to the graph-model integrative thought. Based on the graphic operation platform, the normative equipment mapping library of grid maintenance is established, so that each graphic elements in the platform is one-to-one correspondence with the library data. In addition, the grid maintenance knowledge-base consists of different maintenance rules about electrical equipments and lines. According to the different treatment of the maintenance time, the knowledge-base is divided into fusion rule and mutual exclusion rule. Then the association and interaction between the graphical interface and intelligent analysis for the grid maintenance scheduling are improved. The normative basic data is obtained from the equipment mapping database by heuristic search. On this basis, graphic operation triggers the connectivity analysis, makes obtained basic data associated with the grid maintenance knowledge-base, and then completes the adjustment and compilation interactively. The month maintenance scheduling from Lanzhou Power Supply Corporation is presented as a real-world case to prove the feasibility and scientific of the proposed method.
