摘　　要：介绍了保定热电厂2×125MW双抽机组中DEH对双抽汽的控制情况,系统分析了在中/低压缸抽汽投切工况下DEH对高调门、中调门、低调门的控制以及双抽功能的实现,并简述了抽汽投入后对机组负荷影响的修正情况。This paper introduces the control status of DEH used in 2×125 MW double-extract condensing turbine units in Baoding Cogeneration Power Plant, and analyzes the implement of DEH control to HP, IP and LP regulating valves in the condition of putting into or taking out of service of IP/LP cylinder extractions. The status of the impact on unit loading after the steam extraction being put in service is corrected.
