虚拟蒸馏装置及软测量方法研究

Research of Virtual Crude Unit Construction and Soft-measurement

利用HYSYS流程模拟软件建立虚拟常减压装置,为研究软测量方法提供准确、方便和科学的研究条件。通过对常减压装置负荷变化的真实模拟,探讨了负荷变化对软测量模型泛化能力影响和改进软测量模型的途径。针对基于RBF神经网络常减压装置汽油产品的干点软测量模型的负荷变化问题,提出的改进方法增强了其在实际生产过程应用的适应范围,有利于该方法在实际生产过程中的长期可靠应用。

?An virtual crude unit wich provides accurate,convenient and scientific research condition for softmeasurement method is constructed. Simulating the load changes of crude unit realistically, the effect of load changes to softmeasurement generalisation capability and the approach of improving softmeasurement model are discussed. Aiming at problem of the load changes to the softmeasurement model for the gasoline endpoint of crude unit, the proposed improvement method enforces its adaptability in practical production application and is propitious to its longterm reliable application in practical production.
