摘要
综述了水库调洪演算方法研究进展,对近期典型的计算方法进行了评述与计算效率的实例比较研究;分析了直接试算法的收敛过程,提出了直接试算法的改进迭代格式。改进迭代格式无需计算水位库容函数和泄流能力函数的导数,无需事先确定搜索区间,而且具有较高的计算效率。
This paper summarizes the current status and development of the method tor flood regulating calculation of reservoir, reviews some current typical methods and takes case study as example based on computational efficiency. The convergence of direct trial-and-error method was analyzed, and the improving interactive format of direct trial-and-error method was proposed in this paper, which has high computational efficiency and were not necessary to compute the differential coefficient of function for water level-storage and discharge capacity, to determine the search interval.
