摘要
采用100%容量汽动给水泵配50%容量电动给水泵的机组目前国内不多见。为满足采用这种配置方式的300MW亚临界机组汽动给水泵RunBack(RB)工况,对电泵性能、电泵过流保护、电泵备用状态、汽动给水泵RB时降负荷方式及速度等方面进行了分析,设计了完善的汽动给水泵RB控制方案,并在实际运行中成功应用。
It is uncommon that 100% capacity steam feed pump equipped with 50% capacity electric driven feed pump. In order to meet the requirement of steam feed pump RunBack （RB） in 300 MW subcritical unit, the pump performance, the stand-by state of electric driven feed pump, and load change mode and rate during steam feed pump RB were analyzed. Optimized steam feed pump RB control strategy was designed and successfully applied in practical operation.
