The Research Of Automatic Operational Order Generation System For 110kV Transformer Substation

After expert system technology was introduced to research automatically forming system of operation tickets, many progresses had made at many aspects of the system's performance. But, some faults are still survived at aspects of generalness, real time, etc.An expert system based on frame theory for automatic generating operation sequences of substation is introduced in this paper. The parameters of power system are described with the reproach of frame knowledge representation, and an obvious and clear data structure is constructed. The operating rules of substation equipments are depicted by the reproach of production representation, and a general knowledge data is formed. The equipments' state of the expert system global database is renewed with the real time datum from SCADA (Supervisory Control and Data Acquisition) system. A practical and intelligent expert system has been developed with the combination of expert system theory and the object-oriented language Visual C++.The main distinguishing features of the system are the following:1) The system has interface with SCADA system, and can renew its global database's equipments state with the real time datum form SCADA system.2) The system develops a strong figure software. Users can initialize and modify substation drawing easily.3) The system can apply to all kinds of substations, if some modifications are done to its knowledge base.4) Three modes are provided to form operation tickets, they are automatically forming mode, modifying typical tickets mode and manual writing mode.5) The operating items can be previewed in substation drawing.6) Users are graded according to their purview.
