Abstract

Abstract:

Because the relationship of faults and their expressions in FCCU system is a fuzzy one.The fault diagnosis model was based on the the relationship between FCCU fractionating system malfunction characteristics and malfunction symptoms. This model takes into account the influence of the acquirable symptoms and introduced symptom confidence and rule confidence. The expert knowledge of identifying the fault of FCCU was reviewed. In order to reduce the developing period of fault diagnosis expert system and increase its developing flexibility this paper had discussed a method by using of developing Visual C++ and expert system tool CLIPS the fault diagnosis expert system of FCCU fractionating system. This method has good transplant ability and can develop effective expert system frame in a short time．

Key words:

CLIPS, , VC++, , FCC, , Fault Diagnosis

摘要： 由于催化裂化系统的故障及其表现之间具有模糊性, 针对催化裂化分馏系统故障及特征参数间的关
系建立模糊故障诊断模型, 该模型考虑了已知征兆的影响, 并引入了征兆可信度与规则可信度, 对识别催化裂化分
馏系统故障的专家知识进行了整理。为了缩短故障诊断专家系统的开发周期, 增加开发过程的灵活性, 采用专家系
统工具C LIPS 结合编程语言VC++的方法来实现催化裂化装置分馏系统的故障诊断专家系统。该方法可移植性
较好, 能够在较短的时间内开发出有效的故障诊断专家系统。
