摘要: 流域的退水预报对洪水退水期的水库调度至关重要，直接影响着水库调度效益的发挥。桓仁水库预报模型的7日退水预见期的合格率QR = 100%；确定性系数DC = 0.88。退水预报精度等级接近甲级，达到可利用水平。现以桓仁水库为例，针对综合退水曲线退水段，建立了退水段发电量最大模型，并利用遗传算法对该模型进行求解，最后通过对优化调度结果进行分析，说明了该算法的有效性和优越性，对水库水电站汛期退水段的调度有一定的指导意义。
Abstract: The flow recession forecast is of vital importance for reservoir operation which directly affects the economic benefits. The 7 d flow recession forecast qualification rate is 100% and the determining coefficient reaches 0.88 at Huanren reservoir basin. Since the precision of recession flow forecast is available, a hydroelectric optimal operation model is established for the Huanren reservoir. Genetic Algorithm is used to obtain optimal operation rules and the results are analyzed. It shows the effectiveness and the advantage of Genetic Algorithm, which has a directive meaning for the reservoir’s operation in flow recession period.
