【摘要】 本文介绍了一个基于规则的，应用于电站锅炉优化运行的专家系统，主要用于分析电站锅炉运行中导致排烟损失过高的原因，并提出相应的解决方案，以提高锅炉运行的安全性和经济性。 本文涉及专家系统原理和锅炉原理两方面的知识，以北仑电厂一号炉为实例，介绍了从电厂的原始数据得到诊断结果的整个过程。并且从知识表达和推理策略两个方面详细阐述了优化运行专家系统的形成，包括锅炉对象模型组成、系统数据库的构造、知识库和推理机的实现以及规则库中的各个诊断模型的实现。更多还原

【Abstract】 This paper presents an expert system based on rules for boiler operation in the power plant. It is used for analysing problems that cause exhaust expense to enhance and gives the operator some advises to resolve the problems. It can improve efficiency and security in boiler operations.This paper relates to the principles of expert system and boiler system, and instances a boiler in the Beilun Power Plant to explain the intact process of starting at initial parameters ending in diagnosis results. Then it expatiates that how to build this expert system, including two facets which are knowledge and illation method. It is composed of building the boiler object moduel, constructing the system data base, realizing the knowledges memory and the inference engine and building the diagnosis moduels in the rules memory.更多还原
