摘　　要：通过对目前火电发电机组主蒸汽流量测量方法对比分析,阐述随着机组容量不断扩大和参数的提高,大型发电机组在系统设计时,为了减少压力损失,主蒸汽流量计通常不设,而是利用汽轮机的有关参数间接换算得出主蒸汽流量(也称计算法测量),该方法是大型火电机组主蒸汽流量测量方法的发展趋势。With growing expanse of unit capacity and enhancement of parameter, flow meter is usually not designed for reducing pressure loss during system design for large generator set but making use of relative parameter of steam turbine to get main steam flow by indirect conversion （ called calculation measurement as well） through contrastive analysis of measurement method for current main steam flow of thermal power unit, which is the development trend for measuring main steam flow of thermal power unit.
