某电厂350 MW超临界机组采用基于APS的凝结水系统，该系统功能组主要有2个功能：对凝结水热井至除氧器的凝结水管道段进行注水排气控制；在凝结水变频器启动后，通过凝结水泵再循环阀进行自身循环，为下一功能组进行凝结水管道冲洗做准备。利用功能组成功实现了除氧器上水、凝结水管道冲洗排放、除氧器水位调节阀及凝结水变频调节控制方式的全程自动控制，并减少了运行人员的操作量和操作时间。随着火电机组自动化水平的不断提高，凝结水功能组将得到更广泛的应用。

Through the introduction of the condensate system in 350 MW supercritical unit, analyzed and studied the whole control strategy of condensate water based on automatic startup and shutdown control system. Realized condensate system of automatic startup and shutdown control and could automatically adjust deaerator level and pressure of condensation water pipe. The result is that the whole control strategy of condensate water based on automatic startup and shutdown control system is very good at controlling quality and has a good application value.
