变电站工作票及操作票专家系统的研制

介绍了一套已成功投入使用的变电站工作票及操作票专家系统。该系统的核心模块采用知识工程威廉希尔官方网站 ，开列标准票的知识与经验构成规则库，将变电站的网络拓扑结构建立关系型数据库，推理机动态地操纵规则库和数据库。运用面向对象的继承性来构造软件的类体系，把用于安全措施的成员函数和用于操作的成员函数放入同一个类，实现了工作票和操作票的有机结合。利用Delphi6.0 建立Access 数据库与Excel报表之间的数据通信，实现了自动开票和查询开票的相互转换。

Abstract：An expert system for substation working arrangement & switching sequence is introduced, which has been successfully put into practice. The kernel module of this system adopts the knowledge engineering technology. The knowledge and the experience about generating the standard sequence constitute a rule base. A relational database which stores the network topology of the substation is designed. The inference engine uses the facts and rules to “reasoning” from the rule base and the database. Inheritance of object-oriented programming is used in the design of the software's class hierarchy. The member functions on security measures and the corresponding member functions on switching sequences are placed into the same class; which has realized the organic synthesis of working arrangement and switching sequence. Building up data communication between access database and excel by Delphi，It has realized automatic and inquiry introversion in the way of generating sequences.
