摘　　要：基于汽轮机原理,对现场汽轮机流量特性试验原理以及偏差、要点进行了分析和总结。认为汽轮机流量特性配汽计算只是一个对汽轮机"实际流量-阀位开度"进行标记、映射、还原的过程,而非严格意义上的汽轮机配汽端流动特性的变工况计算。分析、阐述了直接法和间接法两种配汽函数组态模式能达到的理论精度和偏差控制方法,列举了汽轮机流量特性数据整理、应用以及重叠度整定等具体过程的相关要点。Based on the principle of the steam turbine, the Turbine Flow Characteristics Principle and Bias Key Points were analyzed and summarized. Flow characteristics steam distribution calculation is only one pair of turbine ＂actual flow-valve opening＂ marking, mapping, reduction process, is not strictly a steam distribution variable condition calculation. Analyzing and elaborating two methods of steam distribution function configuration mode can achieve theoretical precision and bias control method, Listing the relevant points of turbine flow characteristics data processing, application and overlap tuning other specific process.
