| Operation order expert system is an important measure by which the management department of Power system maintains the economical and safe work of Power system. In view of the necessity for further improvement of the existing Operation order system (OOS) with respect to the intelligence, versatility, easy maintenance and so on, This paper integrated use of platform-based design software ideas, using a client/server model organizational structure, developed entire network integrate intelligent anti-error operation order system for centralized control station, transformer substation section. By using object-oriented approach to knowledge representation, making the model of electrical equipment better, more general; by using the topological analysis method to the design of Inference Engine, making the system more intelligent. Through reference of these new technologies the whole system more perfect, and improving their performance. |
