| Dispatching command order sheets are frequently used in the daily work of regional electric power dispatching, and correctness and security of them are highly demanded. Dispatching command order sheet expert systems are widely used after their emergence, and the efficiency of the dispatching work is enhanced while the workload of the dispatchers is reduced.However, the correctness and security check of the dispatching command order sheets produced is still depended on dispatchers, and their potential impacts on the power system are still estimated by the dispatchers while exact computing is required in certain situations. So, it is necessary to develop a new dispatching command order sheet expert system that roundly considers the correctness proof. With this new expert system, the workload of the dispatchers can be further reduced and the correctness and security of the dispatching command order sheets produced can be well guaranteed.Based on the summarization of the existing dispatching command order sheet expert systems, research in the methods of regional dispatching command order sheets generation, rehearsal, and proof by computers is carried out. Considering the features of regional dispatching, scalability and sharable ability of the regional dispatching command order sheet expert system, dynamic stencils and production rules are used to produced an order sheet; The power system diagrams play an important role in the process of sheet generating, but it is possible for the workers to make some mistakes when drawing the diagrams. Frame theory is used to build up a module to check the correctness of these diagrams and another module to identify the connection modes; A rehearsal platform is provided, and the process of rehearsal is greatly simplified according to the features of the dispatching work of regional electric power systems. Anti-misoperation is realized with switching logics; Power flow computing module is constructed to compute the potential impacts on power flow and voltage of the power system. If necessary, this module will be called by the rehearsal module.A scheme that roundly checks the correctness and security of a dispatching command order sheet expert system is put forward, and realized through... |
