过程控制系统的HAZOP分析

摘要

在过程控制系统中,为了系统地识别运行过程中潜在的安全问题,提出一种危险与运行(HAZOP)分析技术.该技术从化工行业安全分析中发展而来,能够应用于过程控制系统.研究HAZOP分析的基本过程,论述过程控制系统进行HAZOP分析时,设备条目的选取方式、参数和引导词的选取原则,并针对计算机控制化学反应过程系统进行实例分析.%In process control system, in order to identify potential security problem, the analysis technology of Hazard and Operability(HAZOP) is proposed. The technology is developed in the chemical industry, HAZOP analysis can also be employed successfully in computer process control system. In this paper, the procedure of HAZOP analysis is described, followed by the study on the selection of items and the use of parameters and guide words in computer process control systems. The method is illustrated by a case study for the computer control of chemical process system.
