水电工程径流调节和水能计算的改进时历法

指出了《水电工程水利计算规范DL/T-5105-1999》水电站的径流调节和水能计算推荐方法的不甚合理的问题,提出了对规范方法的改进思路和办法。改进方法避免或改正了原规范计算方法分类不合适、部分方法不准确、简化条件不合理等问题。改进方法已通过多项工程实用检验,计算合理、结果准确,能得到比常规方法更大的发电保证出力。

Improved chronological series method for calculations of runoff regulation and water power of hydroelectric projects

This article points out problems in the unreasonable methods recommended in Specifications on water conservancy computation of hydroelectric projects DL/T-5105-1999 for the calculations of runoff regulation and water power of hydropower stations, and suggests ideas for improvement on these methods. It is demonstrated that the improved method can avoid or correct the unreasonableness in method classification, low accuracy in calculation, and indeterminacy in conditions simplifications, etc. The improved method has been verified via application to a number of projects and its calculations are reasonable and more accurate. It could give more firm power output in comparison with the conventional method.
