摘　　要：由于各种因素的影响,汽轮机热力性能试验结果值存在一定的偏差。详细分析了汽轮机热力性能试验测量不确定度的影响因素。以某发电厂330 MW机组汽轮机热力性能试验为例,建立了汽缸效率、热耗率测量不确定度的评定流程,进行了不确定度评定,具有一定的参考意义。Due to various influencing factors, the values of thermal performance test on steam turbine are slightly different. The paper analyzes factors that influence measurement uncertainty of thermal performance test on steam turbine. Taking thermal performance test on 330 MW steam turbine as an example, the paper establishes an evaluation process for measurement uncertainty of cylinder efficiency and heat rate and evaluates the uncertainty, which can be used as reference.
