河口电站位于小凉山下,大渡河畔,属引水式径流电站。设计水头40m,引用流量10.2m~3/s,装机2×1600kW,于1989年建成发电,年发电量1500万kW·h,年均设备利用小时4168 h。该电站安装两台HL220-WJ-84型水轮机。 5年多来,机组运行基本正常,丰水期可超发12.5％,运行安全。不足的是:电站上游山高坡陡,质地松软,植被破坏严重,一到丰水期水中含大量泥沙,且沉沙池 Hekou power station is located in Xiaoliangshan, Dadu River, a diversion runoff power station. Design head 40m, reference flow 10.2m ~ 3 / s, installed 2 × 1600kW, built in 1989 to generate electricity, the annual generating capacity of 15 million kW · h, the average annual equipment utilization hours 4168 h. The plant is equipped with two HL220-WJ-84 turbines. In the past 5 years, the operation of the unit was basically normal, with a 12.5% ​​over-abundance period for safe operation. Is not enough is: the steep mountain slope in the upper reaches of the power station, the texture is soft, the vegetation damage is serious, once arrives the abundant water period the water contains a large amount of sediment, and the settling basin
