Abstract:

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.
