“坝顶门机+厂房活动屋顶布置”首次成功应用于我国西北高寒地区


    直岗拉卡水电站位于青海省西宁市境内黄河干流李家峡电站下游,以发电为主,兼有旅游等综合效益的中型水电工程。2003年开工,2007年建成。低水头径流式电站,河床式厂房,装机容量190MW(5×38MW)。灯泡贯流式水轮发电机组,水轮机转轮直径6.8m,最大水头17.5m,额定水头12.5m,最小水头9.6m。该电站施工4个月后,应业主强烈要求,由澳门金沙城娱乐手机版承担技施阶段后续设计。该工程最大特点:将澳门金沙城娱乐手机版首创的“坝顶门机+厂房活动屋顶布置”成功应用于我国西北高寒地区,运行情况良好;设计优化,澳门金沙城娱乐手机版认真分析了原设计方案,利用同类工程的技术优势,并经模型试验验证,对原已开始施工的方案进行优化设计,其中消能防冲结构缩短一倍以上,使工程节省投资数千万元。

Zhiganglaka Hydropower Station on Yellow River


“Crane on Dam Crest + Plant Movable Roof” is firstly and successfully applied to the alpine region in northwest China.
Zhiganglaka Hydropower Station locates downstream the Lijiaxia Hydropower Station on main stream of Yellow River in Xining of Qinghai Province. The project is a medium-size hydroelectric project with the main purpose of power generation, as well as, accompanied with comprehensive benefits as tourism, etc. Construction of the Project started in 2003 and accomplished in 2007. The project includes a low water head runoff power station and a power house on river channel. With the installed capacity of 190MW (5×38MW), the Station adopts bulb type tubular hydro generating sets. Diameter of the hydraulic turbine runner is 6.1m. The bulb tubular turbine units has maximum water head of 17.5m, rated water head of 12.5m, minimum water head of 9.6m. Four months after its construction, we took the follow-up design of technical construction stage in responding to the strong appeal of the Owner. Typical characteristics of the Project include: It firstly and successfully applied Crane on Dam Crest plus Plant Movable Roof in alpine region of northwest China, and has good operation condition; as well as, it has a rational optimized design. Through thoroughly analysis of the original design scheme, utilizing the technological advantages of the similar projects and being proved by comprehensive model test, we optimized the already started construction schemes. Of the new schemes, the energy dissipation structure has been shortened for more than one half, which saves tens of millions for the project investment.
