摘　　要：为增强给水泵汽轮机系统抗背压扰动的能力,提升机组运行的安全经济性,对某采用给水泵汽轮机直排空冷岛系统方案的350MW超临界机组,针对背压扰动抑制提出相应的优化控制策略。通过仿真分析比较了不同控制方式下背压扰动对系统稳定运行的影响,并结合现场实际应用情况说明了所提出优化控制方案的有效性。In order to enhance the anti-backpressure disturbance of the feed pump steam turbine system and improve the safety and economy of the unit operation,this paper proposes a corresponding optimization control strategy for the back pressure disturbance suppression of a 350 MW supercritical unit adopting the feed water pump steam turbine direct discharge air cooling island system. The effects of back pressure disturbance on the stable operation of the system under different control modes are compared by simulation analysis. The effectiveness of the proposed optimal control scheme is illustrated by the actual application situation.
