实施PID参数整定提高苯酚丙酮装置自控水平

自控水平是企业生产装置安稳运行、高效生产的重要指标,直接影响能耗和产品质量。控制回路能否投用自控、投用效果好坏取决于控制回路的PID参数设置,为了提高自控水平,燕山石化公司与北京化工大学合作陆续对41套生产装置实施了PID参数整定(根据被控变量的特性,合理选择调节器的参数,获得最佳的控制效果,确保控制回路自动安稳运行)。在此基础上实施了自控率监控,保证了PID优化成果。本文以此为背景,介绍PID参数整定在苯酚丙酮装置的应用情况。

Tuning of PID Parameters to Improve the Automatic Control Level of Phenol-acetone Device

Automatic control level is an important indicator for secure operation and efficient production of petrochemical enterprises production device,which directly impact on energy consumption and product quality.The PID parameters of the control loop decide the use of automatic control in control loop and the usage effect.In order to improve the automation level,Yanshan Petrochemical Company cooperated with Beijing University of Chemical Technology implement PID parameter tuning(according to the controlled variable characteristics,choose appropriate parameters of regulator to obtain the best control effect and ensure the automatic safe operation of control loop) of 41 sets of production device.On this basis,we implement automatic control rate monitor to ensure the PID optimization.This article introduced the application of PID parameters tuning in phenol acetone production device.
