摘　　要：介绍了一种核电机组汽轮机性能考核试验的新方法,并利用不确定度理论将其与目前国内常用的试验方法(常规方法)进行了比对分析。结果表明,对于核电机组,新方法较常规方法的试验结果精度高。考虑到新方法测试仪表数量多,测点布置及计算方法复杂,如果非刻意追求更低的试验不确定度,不推荐核电站使用该试验方法。A new performance test method for steam turbines in nuclear power plants was introduced and compared with the current domestic method.The uncertainty theory was applied to analyze the two methods.The results show that,for nuclear power plant,the new method had higher accuracy.Considering the large number of test instruments,the complicated arrangement of the measuring points and the complex calculation method,the new method is not recommended for nuclear power plants,unless deliberately pursuing the lower test uncertainty.
