水文站实测流量资料一般都不长,难以满足水电站、特别是水电站群设计和运行管理的需要。本文用随机过程的理论与方法模拟径流过程的统计特性,建立有效的数学模型,并以黄河上游梯级水电站群为分析计算的实例。 Hydrological station measured flow data are generally not long, it is difficult to meet the hydropower station, especially the design and operation of hydropower station needs. In this paper, we use the stochastic process theory and method to simulate the statistical characteristics of runoff process and establish an effective mathematical model, and take the Yellow River upstream cascade hydropower station as an example for analysis and calculation.
