摘要

对汽轮机热力试验中诸多测量参数的不确定度和最终试验结果的不确定度进行了分析探讨

并给出相应的计算公式。以姚孟电厂 30 0MW汽轮机热力性能试验为例

进行了实际的主流量、主蒸汽流量、发电机出力、热耗率不确定度的计算。

Abstract

The uncertainty of instruments

time

space

mass-flow of fluid

flow coefficient

flow beam expansion coefficient

differential pressure

density

non main flow measurement

electrical power measurement etc. in thermodynamic test of steam turbine

and the uncertainty of final test results have been analyzed and discussed

and corresponding calculation formula is given. Taking the thermodynamic performance test of a 300MW steam turbine in Yaomeng Power Plant as an example

the uncertainty of actual main flow

main steam flow rate

generator output and specific heat consumption have been calculated.
