DCS模块运算顺序重要性

DCS module order of operation importance

针对DCS控制系统中机组DEH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,提出在组态中需按时序顺序排序组态,以解决机组汽轮机冲转升速率不够的问题。

According to the fact that the configuration of DEH control unit in DCS control system affects the unit operation unreasonably because of the timing setting,the monitoring execution cycle and timing are analyzed.It is proposed that the configuration of the DEH control sequence should be sorted in time sequence to solve the problem The problem of not enough speed.
