摘要
介绍了长输液体管道加压站进/出站压力调节的作用方式,提出一种双PID回路耦合的选择性切换控制方法,并以工况分析的形式对低选控制原理和控制流程进行推导和阐述。最后,对低选控制逻辑进行归纳,总结了其特点与适用性。
Regulating the in out - pressure at the long - distance liquid pipeline ＇ s pressure station was de -scribed, and an optional control method with coupling PID loops was proposed, including the deduction of low- selected control principle and control process basing on analyzing the working conditions, as well as summari- zing the low-selected control＇s features and applicability.
