经陕西省计划委员会批复,镇坪县三大峡水电站工程前期工程已全面铺开,进展顺利。 镇坪县三大峡水电站位于曙坪乡境内大曙河中游。三大峡水库枢纽为三等三级建筑物,水库枢纽按50年一遇洪水设计,五百年一遇洪水校核。电站厂房按20年一遇洪水设计,百年一遇洪水校核。 水电站最大坝高60米,坝顶长度150米,总库容量 2027万立方米,工程总投资约 2400至 3000万元左右。机组选用21000+1600千瓦,装机量为3750千瓦,年发电量为1340万度。供电线路为110千伏和35千伏。作为承担峰荷和腰荷的三大峡水电站建成后,将使镇坪县的用电条件得到根本改善。对加速镇坪县的经济发展,满足人民群众从生活需求具有重大意义。 Approved by the Planning Commission of Shaanxi Province, the preliminary works of the Three Gorges Hydropower Station in Zhenping County have been carried out in full swing and progressed smoothly. Zhenping County Three Gorges Hydropower Station is located in Shuping mid-reaches of the river Shuhe. Three Daxia Reservoir hub for the three third-class buildings, reservoir hub floods in 50 years once the design, five hundred floods once checked. Power plant by flood in 20 years design, a hundred years flood check. The maximum dam height of hydropower station is 60 meters, the crest length is 150 meters and the total storage capacity is 20.27 million cubic meters. The total investment of this project is about 2400 to 30 million yuan. Unit selection 21000 + 1600 kW, installed capacity of 3750 kilowatts, the annual generating capacity of 13.4 million degrees. Power lines are 110 kV and 35 kV. As the peak load and waist load of the Three Daxia Hydropower Station is completed, will Zhenping County, the basic conditions for the use of electricity has been fundamentally improved. It is of great significance to speed up the economic development of Zhenping County and meet the needs of the masses of people in daily life.
