糯扎渡水电站水轮机参数选择

The selection of water turbine parameter for Nuozhadu Hydropower Station

糯扎渡水电站单机容量大,机组台数多,水头变幅大。选择机组参数时,既要把改善水轮机运行稳定性放在首位,使机组在投产运行后能承担各类负荷,适应负荷多变的情况,又要使所选水轮机具有国内外同类机组的先进水平。因此,要紧密结合电站的具体情况,尽量参照和采用国内外先进技术,合理地选择确定水轮机主要参数。

With the characteristic of large unit capacity, numbers of units, and width head range, the water turbine parameter selection of the NuoZaDu power station should take it into account, that not only improving the unit operation stabilization i.e. the unit can run stably in different loads and meet the requirement of load change, but also achieving or exceeding the domestic and oversea advanced level. Combining with the power station condition, the domestic and oversea advanced technology shall be consulted for the analyzing and selection of the reasonable water turbine parameter.
