文章结合某煤矿自备电厂锅炉给水系统扰动因素分析,在传统三冲量给水控制策略的基础上,提出以汽包压力微分迟滞信号作为给水流量跟踪副环的前馈量,并延迟给水指令。通过燃烧扰动、蒸发量扰动试验证明,该控制方案具有较强的抗扰动能力。 Based on the analysis of the traditional three-impulse water supply control strategy, the paper proposes the differential pressure hysteresis signal of steam drum pressure as the feedforward quantity of the feed water flow tracking secondary loop, and delays the feedwater instruction. Through the combustion disturbance and evaporation disturbance experiment, this control scheme has strong anti-disturbance ability.
