两台余热锅炉和汽机组成的联合循环机组。其汽机凝汽器采用海水冷却，循环水泵房共设有两台1000kwYZCK－11型循环水泵控制系统，该系统主要以microPLC控制器为核心，按工艺对循环水泵，循泵出口蝶阀，旋转滤网和冲洗水泵的中间逻辑进行处理，实现较为简单的自动控制，故障检测及声光报警。控制方式为为PLC程控硬手操，无工控机。

由于原设计，设备选型的原因，自投运以来故障较多。随着设备运行年限的增长，故障趋于频繁，跳泵故障屡次出现，严重影响燃机的正常运行。主要问题如下：

(1)电源设计不可靠，易引起循泵冷却水压低跳循泵；

(2)循泵出口蝶阀程控不完善， 易引起控制回路故障， 失电， 蝶阀不能自保而关闭， 联动循泵跳闸；

(3)报警系统不完善，无报警记录与历史趋势，难以故障分析；

(4)设备老化，操作复杂，对设备运行的监控及事故的快速反应和处理不利。

这些问题的存在严重影响燃机机组的安全正常运行，不利于机组的稳发满发，有必要对整个控制系统加以改造。
