摘要
羊湖抽水蓄能电站抽水时间多为拉萨电网有多余电量的丰水期，但丰水期正是雅鲁藏布江的丰沙期。为了减少泥沙对水轮机同轴的多级蓄能泵机组叶片等的磨损，因此在抽水系统中设计了沉沙池。本文对沉沙池溢流堰结构布置的设计优化，方便了施工，节约了投资，提高了经济效益，可为其它电站沉沙池结构布置设计的参考。
Water pumping at Yangzhuoyong Lake pumped storage power station is usually at high flow season in which there are excessive electricity in Lasa Electrical Network. However,high flow season is just the silt abundant period in the Yarlungzangbo River in order to decrease the silt wear to vanes of multiple pumped storage unit which is on the same turbine shaft,a setting basin is designed in water pumping system.The optimized design of structural arrangement of overflow wier in setting basin is provided. The optimized design leads to easy construction,less cost and better economic bent fit. It is the reference for structural arrangement of setting basin of other power station.
