句法知识系统在电力调度命令专家系统中的应用

THE APPLICATION OF SYNTACTIC KNOWLEDGE SYSTEM IN POWER DISPATCHING COMMAND EXPERT SYSTEM

电力调度命令专家系统的任务就是如何根据运行规程、调度人员的知识和当前系统的状态,正确地生成操作票.本文从模式识别的角度出发,将句法知识系统中的EDS算法作为推理机应用到电力调度命令专家系统中.提出了"虚拟操作票"的概念.并解决了EDS算法在应用中可能存在的问题.

The task of the power dispatching command expert system is to build up the operation sequence correctly based on the power system dispatching specification, the experience of the human operators and the current state of power system. In this paper, from the viewpoint of pattern recognition, the application of EDS algorithm in syntactic knowledge system used as the inference engine of this expert system is presented, the idea of virtual operation sequence and the method of avoiding the left-recursion that possibly exits in the application of EDS algorithm are also proposed.
