Design and operation

The Dongfeng is a Шаблон:Convert tall and Шаблон:Convert long parabola-shaped arch dam. The dam is Шаблон:Convert thick at its crest and Шаблон:Convert at its base. It sits at the base of a catchment area covering Шаблон:Convert. The total reservoir capacity is Шаблон:Convert while Шаблон:Convert is for regulating. At the reservoir's normal elevation of Шаблон:Convert above sea level, the reservoir capacity is Шаблон:Convert. The dam has several discharge facilities; three spillway gates near the crest, three intermediate orifice openings, one chute spillway on the left bank and beside it, one spillway tunnel. The maximum discharge capacity of the spillways is Шаблон:Convert while all openings, including the power station tailrace, can discharge Шаблон:Convert. The power station is located underground on the right bank of the dam. The intake releases water to three headrace tunnels which transfer into penstocks and supply each of the 190 MW Francis turbine-generators. Water is discharged back into the river via one tailrace tunnel.[1][2][3]
