摘　　要：文章全面介绍了燃气-蒸汽联合循环机组中高压给水泵在变频器“一拖二”工况下,通过优化控制逻辑,实现机组在启动与低负荷状态时既能实现变频器根据汽包压力自动控制给水压力降低能耗,又能保证备用泵可投入自动联锁,为机组稳定运行奠定基础。In this paper,it is comprehensively introduced the energy consumption is reduced by automatically controlling feed pressure based on the drum pressure by frequency converter and stand by pump is ensured to be put into automatic interlocking when the unit is started and in the condition of low load through optimizing control logics under the working condition of“one with two”for frequency converter of high pressure feed pump in the gas-steam combined cycle unit,which lay the foundation for stable operations of the unit.
