西洱河一级电站,设计安装了3台高水头混流式水轮发电机组。水车机部分基本数据: 型式 HLA_(41)—LJ—190 设计水头 220米最低水头 208米最高水头 245米设计流量 18.5立米/秒设计出力 36200千瓦额定转速 500转/分飞逸转速 840转/分吸出高程 -4.5米(-6米) 轴向推力 82吨发电机部分基本数据: 型号 TS384/140—12 额定功率 40000/35000KVA/KW 额定电压 10500V 额定电流 2200A 额定功率因素 0.875 相数 3 额定转数 500R.P.M. 飞逸转数 830R.P.M. 转动惯量 300T—M~2 短路比 1.035 电站一、二号水轮发电机组于79年下半年安装试运转,80年1月3日完成满负荷72小时试运行,移交生产投入系统。高水头混流式水轮机在吴河、绿水河、渔子溪电站的安装、试运转中都碰到了压力脉动引起的水轮机振动问题。
Xi’erhe first-class power station, designed and installed three high-head Francis turbine units. Water machine part of the basic data: Type HLA_ (41) -LJ-190 Design head 220 meters Minimum water head 208 meters Maximum head 245 meters Design flow 18.5 cubic meters / second Design output 36200 kW Rated speed 500 r / g Flyaway speed 840 r / Sub-suction elevation -4.5 m (-6 m) Axial thrust 82 tons Generator part Basic data: Model TS384 / 140-12 Rated power 40000 / 35000KVA / KW Rated voltage 10500V Rated current 2200A Rated power factor 0.875 Number of phases 3 Rated rotation 500R.PM Running speed 830R.PM Moment of inertia 300T-M ~ 2 Short circuit ratio 1.035 Hydroelectric generating units No. 1 and No. 2 were installed and commissioned in the second half of 79, and were completed at least 72 hours on January 3, Trial operation, transfer of production input system. High head Francis turbines encountered turbine vibration problems caused by pressure pulsation in the installation and commissioning of Wuhe, Lushuihe and Yuzixi Hydropower Plants.
