| 摘 要： | 随着国内抽水蓄能电站的广泛建设,通过对渗流量等原型观测资料的分析,可以揭示可能来源于输水系统的"内水外渗"状况.与常规水电站不同,针对抽水蓄能电站特殊的运行工况,建立了以日为变化周期、小时为计算单位、同时考虑滞后效应的渗流统计模型,并采用遗传算法求解滞后因子.计算实例表明,该模型具有较好的拟合精度;区内不同测点渗流量主要受上库水位因子影响,但滞后因子存在显著差异.因而认为,该模型具有较强的工程实际意义.

| Abstract: | With the wide construction of pumped storage power stations in China,the seepage situation potentially originated from the conveyance system may be revealed the analysis of the prototype observation data for seepage amount.In the special case of the pumped storage power stations which are different from the general hydropower stations,a statistical model for the seepage is established based on the lag effect,which takes an hour as the unit and a day as the period.The lag factors are calculated by use of the... |
