摘要: 介绍了核电站汽轮机及其热力系统的基本特点以及蒸汽湿度的测量方法。分析了蒸汽湿度的变化对汽轮机进汽比焓、试验结果的修正及试验总不确定度的影响。在压水堆核电站汽轮机热力性能试验中,某些情况下可采用蒸汽发生器出口处的设计湿度来计算进汽湿度,作为直接测量湿度的替代方法。

Abstract: The basic characteristics of nuclear power station steam turbine with its cycle are introduced, as well as the measurement methods of steam moisture. The effect of the changes of steam moisture on steam turbine inlet enthalpy, corrections of test results and total test uncertainty were analyzed. It is presented that in the pressurized water reactor nuclear power turbine performance test the design moisture at outlet of steam generator can be used to calculate the inlet steam moisture under certain circumstances as an alternative method to take place of direct measurement of moisture.
