针对DCS成组控制系统中机组负荷控制组态因时序设置不合理影响机组运行的情况,分析监控执行周期和时序,介绍DCS时序设置原则,提出在监控组态中需按时序顺序排序编程,并改进成组控制程序,以解决负荷控制波动问题。
Aiming at the situation that unit load control configuration in DCS group control system is unreasonable due to unreasonable timing setting, the monitoring execution cycle and timing are analyzed. The principle of DCS timing setting is introduced. It is proposed that sequencing should be programmed in sequence Improve group control procedures to address load control fluctuations.
