| 摘 要： | 通过对大坝电厂^#1机组全程给水自动控制系统的分析、试验以及组态修改，对两台汽动给水泵调速特性的区别在组态上进行了修正，避免了两台泵出现交替互堵和抢负荷现象，使减温水压力得到了保证。实现了汽动给水泵组在机组低负荷滑压运行时投入调泵方式。为机组的安全稳定运行奠定了基础。

| Abstract: | By analysis, test and configuration reformation for the whole process of feed-water automatic control system in No.1 unit of Daba Power Plant, revises the speed control characteristic of two vapor driving feed-water pumps from their configuration, avoids the alternative blocking up and vying for the load between two pumps each other, ensures desuperheafing water pressure, during low load sliding pressure operation, realizes the pump adjusting mode of vapor driving feed-water pumps, establishes the foundation for the units safe and stable operation, |
