摘　　要：超临界直流炉的给水控制技术是目前国内热控领域一个重要的研究课题,干态过程的给水自动控制在电厂应用中比较成熟,而湿态给水自动控制效果相对而言并不理想。本文以利港电厂600 MW超临界机组给水系统为对象,提出了实现湿态给水控制系统的新型的控制策略及湿态给水控制系统投入运行后的相关参数和运行曲线,为国内外超临界直流机组湿态给水控制方案的设计及调试提供了参考和借鉴。The feedwater control of super critical once through boiler is an important study subject in thermal field at present. In practice, the water control above the benson point is more mature than before all water is converted into steam. The article presents a new automatic control at low loads as well as some correlative parameters and operation trends by an instance of 600 MW unit of Ligang Power Plant. This study would provide reference for the design of automatic control and commissioning of similar units.
