It is an annual regulation reservoir. This hydroelectric power station is mainly designed for generating electricity. It gives consideration to shipping, transporting wood and preventing waterflood as well. The water retaining structure of Bailianya hydroelectric station is a concrete gravity dam. The damsite is at Manshui Rver. The vally at that locality is appropriately narrow. The terrain of two riversides is symmetrical. The rock is simply posed of granite porphyry which is solid and plete. So the geological condition is good. This dam’s normal water level is 208m, and its corresponding storage capacity is billion cubic metres. The monthly average rate of flow is cubic metres per second at the damsite due to longterm statistics. It is an annual regulation reservoir by calculation.In my graduation project the impounded level was originally designed to be 211m. Because this reservoir got little water supplement annually, the normal water level was reduced to be 208m according to the calculation of water equilibrium regulation. By profiting regulation and waterpower calculation, the 179mdead water level was eventually chosen from three draft dead water level schemes(179m, 181m, 183m) because its ensuring output is the largest one. The corresponding storage capacity is 55 million cubic metres. The flood control water level was designed to be 207m. On the basis of protection standard of downstream structures(P=1%), the upper water level for flood control was designed to be . According to the data of the design flood, the design flood level was designed to be . According to the data of the check flood, the maximum flood level was designed to be .The crest altitude of the nonoverflow dam section of Bailianya hydroelectric station is 215m. Its maximum height is 82 metres. The base of the dam is 68 metres wide. The altitude of the weir crest of the overfall dam section is 202m. The clear widith of the spillway is 60 metres. The sluice gate is metres wide and 7 metres high. The gate pier is metres long and 3 metres thick. The overall length of the spillway is 78 metres. The base of the overflow dam is metres wide. The overall III / 78length of the water retaining structure is 300 metres.By calculating the balance of the electric energy balance, the installed capacity of the hydroelectric station was designd to be 86 thounsand kW. It was divided into two units whose unit capacity was 43 thousand kW. The model of the water turbine is HL220LJ380. The factory building was designed to be the dam type. Its main factory was designed to be 20 metres wide and 55 metres long. The installation altitude of the water turbine was . The electrical double hook bridge crane was chosen. Its maximum hoisting capacity is 2150t. The span was chosen to be 16 metres. The assembly plant was designed to be 20 metres long. The auxiliary room was designed at the downstream side of the main factory for ensuring that the station was working regularly. It mainly contained various of electromechanical aids, manufacturing shops and some necessary domestic installation rooms. The auxiliary room was metres wide.This electrical station will join the East China Power Grid after the construction work is finished. Furthermore, the construction of the station will drive the local agriculture into further development and create more employment opportunities for local residents. It willimprove the social economy and promote local area and its surrounding areas’
