汾河灌区水资源联合调度
|
摘要
根据汾河灌区各类水资源不同的水质水量,制定供水原则,将灌区内水资源系统分为3个子系统,建立了灌区水资源系统调度模型。以多年平均缺水量最小为目标,以2座梯级水库为核心,制定水资源系统常规调度规则;以多年平均缺水量最小为主要目标、年发电量最大为次要目标进行水资源系统优化,采用分层序列法将多目标转化为单目标,即在满足主要目标的可行解内选择满足次要目标的最优解。优化结果表明,与常规调度结果相比,水库综合供水能力有所提高,地下水多年平均引水量有所减少,而区间多年平均引水增加,灌溉用水保证率与生态用水保证率都明显提高,多年平均发电量和稳定发电时间均有所增加,证明该方法是合理可行的。
Based on the quality and quantity of water resources in Fenhe irrigated area,the principle of water supply is made. The water resources system in Fenhe irrigated area is classified into three subsystems,and the scheduling model of water resources system is established. Taking the annual average minimum water shortage as the object,and two cascade reservoirs as the core,the conventional dispatching principle of water resources system is established. Taking the annual average minimum water shortage as the main object,and the maximum volume of electricity production as the secondary,the optimization of water resources system is conducted. Based on the delaminating sequence method,the multi-object is translated into single-object,that is to say,while the feasible solution can meet the main object,the optimum solution meeting the secondary object is chosen. Compared with the conventional dispatch result,the optimized result shows that the comprehensive water supply capability of reservoir is improved,the average diversion of underground water for years is reduced,the interval average water diversion is increased,the guarantee rate of irrigating water and ecological water is improved obviously,the average generated energy for years and the water quality during power generation time are increased. So the method is reasonable and feasible.
