摘要
针对在枯水期葛洲坝大江和二江电站机组发电水头存在较大偏差现象,根据对水头偏差的分析,得出水头偏差受下游水位影响较大,利用以出库流量作为输入因子的下游水位经验递推方法,计算水头偏差,结果与实际相符合。在水头偏差分析的基础上,给出了利用水头偏差可能产生的经济效益。
The generating water head has large difference between the Dajing and Erjing power plants of Gezhouba Hydropower Station in dry season. The analysis shows that the head deviation is mainly depended on tailwater level. Taking outflow as an input factor of downstream level recursive method, the head deviation is calculated. The calculation is consistent with actual measurement. The economic benefits of generation based on head deviation are also analyzed.
