针对2011年全国性小水电站增效扩容项目文件中对老旧水电站更新改造的要求,在开展农村水电改造设计过程中,遵循《小型水电站水文计算规范》和《小水电水能设计规程》的规定,总结了有实测径流资料、引用相邻或相似流域水文资料、无径流实测资料三种条件下小水电站的水文径流和水能计算方法,并结合三座电站运行多年的统计数据进行核算或反推,求出拟改造条件下水电站水能指标,以此判断设计电站是否满足电量计算的增效扩容潜力不低于10%的要求。
According to the requirements of the renovation and renovation of old hydropower stations in the project of efficiency expansion and expansion of national small hydropower stations in 2011, in the process of carrying out the rural hydropower reform and design, follow the provisions of Hydrology Computation for Small Hydropower Plants and Design Rules for Small Hydropower , Summarizes the hydrological runoff and water energy calculation methods for small hydropower stations under three conditions: measured runoff data, hydrological data from adjacent or similar drainage basins, and measured data without runoff. Based on the statistical data of three hydropower stations operating for many years, Push and find the hydropower index of the hydropower station under the conditions of the reconstructed project so as to determine whether the design hydropower station meets the requirement of not less than 10% of the synergistic expansion potential calculated by the power plant.
