摘要

以某330 MW机组为例

给出了在线计算凝汽器真空应达值的方法

此方法经过1次计算即可得出凝汽器的真空应达值

而无需经过迭代计算和网络参数的训练。在线计算出的凝汽器真空应达值可为运行提供指导

其与真空实际值的差值还可作为凝汽器空气漏入量的在线监测依据。

Abstract

Taking a 330MW unit as the example

a method to determine the norm vacuum of condensers which is difficult to measure was presented.By this method

no iterative computation and network parameter training was necessary

the norm vacuum of condensers can be obtained through only once calculation.The online calculated norm vacuum of condensers can provide economic operation guidances for the operating personnel.Moreover

difference between the norm vacuum and actual vacuum can be used as the basis of online monitoring for amount of air leaking into the condenser.
