【摘要】：传统的水库调度以兴利调度和防洪调度为主,常忽视生态环境问题,导致河流生态水文系统的健康状况不断恶化。相对传统的以水电站年发电量最大,发电保证率最高为目标函数,本研究还引入了生态保证率最高的目标函数,构建基于生态流量区间的多目标水库生态调度模型,并采用NSGA-Ⅱ算法对模型进行优化求解。利用该模型对天生桥一级水库1956年-2008年的来水过程进行优化调度,结果表明:经济效益最大的调度方案会对天然径流过程产生显著的改变,而兼顾经济效益和生态目标的建议调度方案对水库的经济效益产生影响较少的同时能保证生态系统的稳定性。
[Abstract]:The traditional reservoir dispatching is based on the beneficial operation and flood control, and often ignores the ecological environmental problems, which leads to the deterioration of the ecological and hydrological system of rivers. Compared with the traditional objective function of the maximum annual electricity generation and the highest power generation guarantee rate of hydropower stations, this study also introduces the objective function of the highest ecological guarantee rate, and constructs a multi-objective reservoir ecological dispatching model based on the ecological flow range.
