摘要 庆元抽水蓄能电站位于山区,上下水库坝址流域面积小,水文观测基础条件有限。降雨径流模型法主要基于长系列降雨观测资料,借助邻近流域水文站资料建立降雨径流模型并移用至本流域,对逐日径流过程进行模拟优化。径流成果更符合小流域特征,对于分析庆元抽水蓄能电站水源条件能提出更为可靠的设计成果,也为同类型抽水蓄能电站小流域径流计算提供参考价值。 Qingyuan Pumped Storage Power Station is located in a mountainous area with small watershed areas at the upper and lower reservoir dam sites and limited hydrological observation data.The rainfall-runoff model method is primarily based on long-term rainfall observation data and utilizes hydrological data from nearby basins to establish a rainfall-runoff model that can be applied to this basin for daily runoff process simulation and optimization.The resulting runoff data better reflects the characteristics of small watersheds,and provides more reliable design results for analyzing the water source conditions of the Qingyuan pumped storage power station.It also provides valuable reference for runoff calculations in similar pumped storage power stations in small watersheds.
