水库常规调度图逆推计算问题分析

针对水库常规调度图绘制过程中的逆推计算问题,从完成水库调度任务、充分发挥水库水头效益、避免水库供水后期集中破坏等方面将逆推计算结果与顺推计算结果进行了详细的对比,分析总结了水库常规调度图绘制采用逆推计算而不采用顺推计算的优势。最后从提高水资源利用率和保障水库安全运行的角度解释了绘制加大出力线采用偏枯来水过程而绘制降低出力线采用偏丰来水过程的原因。

Simple analysis on the reverse calculation of conventional reservoir scheduling figure

Aiming at the reverse calculating problem in drawing conventional reservoir scheduling figure, this paper compared the reverse calculating results with the forth calculating results in details from the aspects of completing reservoir scheduling task and getting more benefits of the reservoir water head and avoiding late concentrated destruction of water supply, etc. Analyzed the reasons and summarized the advantages of using reverse calculation instead of using forth calculation in drawing conventional reservoir scheduling figure. Finally, from the perspective of raise the utilization ratio of water resources and guarantee the safe operation of the reservoir, this paper gave the reasons why we using dry year water process to draw the increased output line and using wet year water process to draw the reduced output line.
