Study on Layout of Diversion Underground Powerhouse and Switch Station of Changbo Hydropower Project
Combining with the topography and geology,layout of water conveyance and power generation sys-tem,engineering construction,operation and maintenance of Changbo Hydropower Project,the layout of diver-sion powerhouse and switch station is studied and compared.Finally,it is determined that the diversion power-house is arranged in the ridge about 500m upstream of Moqu Estuary,and the tail underground powerhouse is adopted.The longitudinal axis direction of the powerhouse is N73°W,and the switch station is arranged at the bend of the highway upstream of Moqu Estuary,and the ground switch station is adopted.
