小型径流式水电站装机容量的确定,是通过对径流系列进行分析,对来流大小进行排频,并利用列表法计算电站不同装机容量对应的发电效益及年利用小时,引入经济指标,估算其投资效益比,选取适合小型水电站的合理装机。该方法可有效指导小型径流式水电站的装机复核,也可为类似工程提供一定的参考。
The determination of installed capacity of small-scale radial-flow hydropower stations is based on the analysis of runoff series to rank the size of incoming flows and calculate the generation efficiency and annual utilization hours corresponding to the different installed capacity of power plants by using the list method. Economic indicators are introduced to estimate the investment Benefit ratio, select suitable for small hydropower station installed. This method can effectively instruct the installation review of small-scale radial-flow hydropower stations and provide some reference for similar projects.
