摘　　要：介绍一种基于MS-Access的框架知识表示法。采用这种方法建立电力系统网络的关系参数库,给出了发电机、输电线路、开关、母线等电网元件及各元件间的连接关系。针对实际电力系统短路计算数据的要求,用ADO(ActiveXDataObjects)技术对数据库编程,根据已知电力元件、设备参数等,利用人工智能的广度优先搜索技术,遍历网络相关元件,进行拓扑分析,生成短路计算用的数据。进行了简单的实例分析,该方法已应用在地区电网继电保护整定计算中,由实际电网参数库生成了整定所需的短路计算数据。A frame knowledge representation based on MS-Access is introduced,with which a rela-tional database of power network is established.The power network components,such as generator,transmitting line,switch,bus,etc.,and their connective relationships are given.Programmed with ADO(Active X Data Objects)technique and according to network component parameters,the data for short current calculation are gotten using the breadth-first search with artificial intelligence and the topology analysis.A simple example is put forward.The method is applied in relaying protection calculation,in which the data for short current calculation are generated from actual power network database.
