油田脱水转油站计算机集散型控制系统

Computer based Total Distributed Control System for an Oil Field Dehydration and Oil Transfer Station

文中较全面地论述了油田脱水转油站计算机集散型控制系统。讨论了油水界面的测量方法，计算公式和控制原理。在国内首次选用美国霍尼韦尔双法兰差压变送器智能表测量油水界面，用计算机实现闭环控制，取得满意效果。该系统也适用于其它复杂工艺过程的控制。

A fairly comprehensive description is given of a computer based total distributed control system for an oil field dehydration and oil transfer station.Discussed are the method for measuring oil water interface,calculation formulas and control principles.It is the first time in China that a dual flange differential pressure intelligent meter of US Honeywell Co.make has been used for the measurement of oil water interface.With the help of a computer satisfactory results are obtained with the realization of a closed loop control. The proposed system can also be employed for the control of other complicated technological processes.
