HYSYS软件及其自动化接口研究

复杂系统的故障诊断,由于潜在故障的数目极大,因此无法对诊断方法的实际效果进行有效地评价和验证.在化工流程中这一矛盾更加突出.考虑运用仿真技术搭建“虚拟工厂”,并利用计算机自动进行事故的产生,来对各类诊断方法进行综合评价.由于化工流程的多样性,要求虚拟工厂能模拟各种流程,且具有开放性、可扩展性以及动态模拟等特性,选用HYSYS作为仿真平台.针对该平台进行的事故产生和实时数据监测都涉及到与HYSYS的数据交互问题.该文对基于HYSYS进行的诊断方法评价环境作了介绍,并重点对利用其自动化接口进行不同进程间数据交互的问题进行了详细的研究.此研究对于故障诊断的验证方法有积极意义.

HYSYS and its Automation Interface

As far as the fault diagnosis of complex system is concerned,because the number of the potential fault is large,the factual effect of the fault diagnosis methods cannot be assessed and validated effectively,especially in chemical processes.Just for this reason we consider using simulation technology to put up " the fictitious factory ",and utilize the computer to carry on the production of the faults automatically,to carry on comprehensive assessment to all kinds of diagnosis methods.Because of the variety of the chemical process,we require the fictitious factory to imitate various kinds of procedure,and have characteristics,such as opening,expansibility and dynamic simulation,etc.So we select HYSYS as the simulation platform.The production of faults and the real-time data monitor both come down to the data permutation with HYSYS.In this work,the assessment circumstance of faults diagnosis methods based on HYSYS is introduced,and the utilization of its automation interface for carrying on the data permutation in different processes is studied in detail.This is good for diagnosis method's validation.
