摘要
针对SL 76—2009《小水电水能设计规程》中缺少以灌溉为主的小水电水能计算方法,而设计工作中常用的计算办法存在一些不合理之处的问题,在分析常规方法不足的基础上,提出了一种改进的计算方法——长系列连续时历法,改正或避免了常规方法不合理的假设条件、简化计算等问题。实际工程应用结果表明,采用改进方法计算可提高小水电发电和灌溉运行的合理性,适用于不同调节性能的水库,可以得到比常规方法更多的灌溉水量和更好的发电指标。
Hydro Energy Design Code for Small Hydropower Projects （ SL 76-2009 ） lacks a calculation method for hydro energy of small hydropower, mainly for irrigation, and the calculation methods commonly used in designing work are not usually reasonable. Based on analysis of the disadvantages of conventional methods, an improved calculation method, the long series calculation method, is put forward, correcting or avoiding such problems as the unreasonable assumed condition and the simplified calculation of conventional methods, etc. The results of application of the improved calculation method in practical engineering show that the improved calculation method can improve the rationality of operation of small hydropower generation and irrigation, and it can be applied in reservoirs with different regulation performance, obtaining more irrigation water and electricity production as compared with conventional methods.
