联合站的生产流程中都存在自动控制系统,一个自动控制回路一般由四个环节组成,每个环节出现故障或扰动都使得自动回路无法正常运行。在系统投运时经常遇到一些故障,造成控制系统无法实现闭环控制,甚至影响到安全生产。本文从这些故障入手,分析产生原因,并采取相应的措施,从而使联合站自控系统实现正常的自动控制。 There are automatic control systems in the production process of the joint station. An automatic control loop generally consists of four links. Each link failure or disturbance makes the automatic loop unable to operate normally. In the system put into operation often encounter some failures, resulting in control system can not achieve closed-loop control, and even affect the safety in production. This article starts with these faults, analyzes the causes and takes corresponding measures, so that the automatic control system of Union Station can realize the normal automatic control.
