蒲石河抽水蓄能电站水沙调度方案研究

Pushihe Pumped Storage Power Station Water and Sediment Control Scheme

抽水蓄能电站往往有两个独立的水库,不存在水沙调度的问题,而位于天然河道上的常规水电站的水沙调度往往只受天然入库流量,不受机组发电流量的影响,因此为了研究下水库中泥沙与抽水蓄能机组的相互影响,编制了抽水蓄能电站水沙调度方案。文章从水库泥沙特性、泥沙对机组影响、泥沙对上水库淤积、水库排沙后回蓄等方面进行了分析研究,综合比较各预设方案制定了符合现场实际的水沙调度方案,该方案对下水库处于天然河道的抽水蓄能电站有着借鉴和参考的意义。

Pumped storage power station tend to have two separate reservoirs, water and sediment scheduling problem does not exist, water and sediment scheduling of the regulation station located on a natural river is often affected by natural inflow only, without generating units flow, so in order to study of mutual influence of reservoir sediment and pumped storage units, working out the pumped storage power station water and sediment scheduling scheme. Articles from the reservoir sediment characteristics, sediment impact on the unit, sediment on the reservoir sedimentation, sediment back to the reservoir storage and other aspects of analysis, comprehensive comparison of each preset programming scheduling scheme in line with the water and sediment of the actual site, the program for the lower reservoir of natural river in the pumped storage power station with a reference for meaning.
