摘　　要：水电站在设计初期需要选择相似模型综合特性曲线进行过渡过程计算,以初步确定调节保证设计目标参数。本文以国内黄河上游某大型混流式水电站在设计之初选择的模型综合特性曲线为例,对比了机组招标之后为本电站开发的模型综合特性曲线A和设计初期选用的模型综合特性曲线B过渡过程计算结果的偏差,分析采用不同模型综合特性曲线对机组过渡过程计算几个主要控制特征值的影响。At the early period of designing a power station, it is requied to choose the similar model comprehensive characteristic curve calculations to determine the adjustment and ensure the preliminary design target parameters for transient process. This article compares the deviation of the calculations results between a model comprehensive characteristic curve A developed for this power station which is the upstream of the Yellow River after the units5 tender and comprehensive model characteristic curve B chosed at the early stage of the design, and analyse the effect to adopt the diffrent models comprehensive characteristic curve control characteristic values of the transient process unit.
