The multi-annual mean amount of runoff of Taizi River basin is about 4.6 billion m3, which is the richest river in Liaohe River various branches in water volume. The flood of this basin is produced by rainstorm, the number of times is frequent, the sudden rise drops sharply, the flood peak is especially big. In addition, the coast beware of Taizi River is weakly, the amount of flood control discharge is limited. Therefore the flood along the river is severe. In order to meet the requirements including flood control, waterlogging control, industrial and urban water, irrigation water and power generation of Taizi River basin, Guanyinge reservoir would be built on Taizi River. Guanyinge hydroelectric power station project includes the design calculation of runoff regulation and water, hydro generator selection, flood regulation, dam design, hydropower plant layout, erection bay’s floor structure calculation. It can be known from the calcuation that the usable storage of Guanyinge reservoir is , the normal pool level is 231.66m; the selected turbine type is HL240-LJ-180, generator model is SF8-12/312; the desig
