摘　　要：对湘潭1,2号机组DA S系统主蒸汽流量指示值出现偏差的原因进行分析,找出原计算模型中存在的问题。将机组热力性能试验的主蒸汽流量与DA S系统指示的主蒸汽流量值进行比较后,确定了新的主蒸汽流量与调节级后压力等测量参数的对应关系,并提出了对原计算模型的修改意见。Deviation causes of main steam flow value indicated in DAS system for Xiangtan power plant unit 1 and unit 2 are analyzed in this paper and problems existing in the original calculation model are found, A new relationship between main steam flow ahd other parameters such as pressure after regu（ating stage is established after comparing main steam flow of performance test and the main steam flow value in DAS system. Finally, modification suggestion of original calculation model is presented.
