电网调度操作票专家系统中的知识表示方法

针对以往操作票专家系统中电网一次接线图与其拓扑结构知识库相互独立，分别由两个功能模块单独管理带来的不便，重点论述了基于图形界面的地区电网调度操作票专家系统中的知识表示及获取方法；提出了一种基于图论中“关联集”的框架结构表示电网拓扑结构知识的方法及其自动获取，这种方法原理简单、构思新颖、完全可以表示复杂的电网结构。介绍了“扩充的‘规则架＋规则体’模式”对操作规程中领域知识的描述形式及其推理机制。

Knowledge Representation Method in Power Network Dispatching Command Order Sheet Expert System

To deal with the problem of lack of suitable KR method in previous District Power Network Dispatching Command Order Sheet expert system with graph interface (DPNDCOS),which makes it difficult to directly connect the graph with its topology stucture knowledge,this paper discussed in detail the method of knowledge representation and knowledge acquisition used by DPNDCOS,then puts forward a frame stucture based on “incidence set of graph theory”to represent power network topology stucture knowledge,which is easy to be obtained by network graph,finally instructs the visualized mode of the expanded“Rule Skeleton+Rule Body”used to express rule knowledge base and the inference engine
