超高压变电站警报处理和流图解释专家系统

AN ALARM PROCESSING EXPERT SYSTEM FOR EHV SUBSTATION AND FLOW GRAPH EXPLANATION

研究用于超高压变电站(EHVS)警报信息处理的专家系统(APES),解决了EHVS发生故障时,大量警报信息超出运行人员的反应和综合判断能力,无法迅速、有效排除故障的问题。APES对警报信息作智能压缩处理,提炼出关键的警报信息。本文提出一种新的流图解释结构,克服常规的文字解释速度慢、难于被用户理解和接受的缺点,更适应现场人员形象理解问题的习惯,增强了APES的透明度和实用性。

An alarm processing expert system (APES) for EHV substation is described in this paper. When faults ocuur, alarm messages may be so many, and alarms may change so fast that a full CRT screen may not be able to display, and the opeator may not be able to anylyze and judge. The APES can compress the messages intelligently and extract key messages. This paper also presents a new structure of explanation—the flow graph explanation.
