一种基于多层流模型的核电厂智能报警分析系统

A Nuclear Power Plant Intelligent Alarm Analysis System Based on Multilevel Flow Model

围绕核电厂报警分析展开研究,结合多层流功能建模方法,提出并开发了一套基于有向图知识表达的智能报警分析系统。以压水堆主冷却剂系统左环路LOCA事故工况为例,对所提出的智能报警分析系统进行了验证,结果表明该系统可以过滤信息并定位根原因,通过图像信息呈现方式为操纵员提供有效的综合诊断信息,降低大量信息对于信息诊断任务的影响,提升核电厂运行的安全性和可靠性。

This article focused on nuclear power plant alarm analysis,and combined with the multilevel flow functional modeling methods,it proposed and developed a set of intelligent alarm analysis system based on the knowledge expression of directed graphs.The left loop LOCA accident of the main coolant system of the PWR working conditions was taken as an example,the proposed intelligent alarm analysis system was verified.The analysis shows that the system can filter invalid information and provide the operator with effective comprehensive diagnostic information through image information presentation,so as to reduce the impact of a large amount of information on the information diagnosis task and to improve the safety and reliability of the nuclear power plant.
