| Abstract: | Four adjustable blade propeller turbine of 100MW each and one 20MW Francis turbine are installed in Longkou Water Control Project.It is predicted that the mean annual sediment concentration is 6.80 kg/m3 and maximum sediment content is 283.9 kg/m3 after the reservoir is completed.Two factors are considered in hydraulic machinery design,first,prevent erosion of sediment to turbine and technical water supply shall guarantee safe operation of the unit in flood season;and second,play high efficiency of unit in dry season for more power generation. |
