摘要
根据差积曲线和满库曲线,利用图解法进行等流量调节是兴利调度的常用方法。为提高图解法的计算效率和精度,将图解法中的差积曲线、满库曲线视为弯曲走廊边界,提出弯曲走廊最短路径算法并实现程序化,得到的最短路径即为时历图解法的调节线,进而求出各时段的调节流量。工程应用案例分析表明,该算法合理有效,可推广应用至多年调节和年调节水库水能计算中。
Based on residual mass curve and full reservoir curve, constant flow scheduling by using the graphical method is commonly applied in reservoir beneficial purpose regulation. To improve the efficiency and precision of the graphical method, residual mass curve and full reservoir curve are regarded as a tortuous corridor and the shortest path algorithm is put forward where the shortest path can be considered the best dispatch curve. The regulated flow can be solved by using the shortest path. The case study indicates that the algorithm is effective and thus can be applied to calculate the hydropower in regulating or annual regulating reservoir over the years.
