【摘要】 采用美国陆军工程兵团的水库调度软件模型HEC-ResSim对清江梯级水库进行了模拟调度演算和效益评估。模型分别选用1955～2005年丰、平、枯典型年3小时历史实测径流资料,通过与常规调度方法的结果相比较,提出了适宜于该流域梯级特性的调度规则。模拟研究的结果表明,HEC-ResSim模型对于丰水年、平水年以及所有年份的蓄水期调度效果优于常规的方法,而在枯水年及所有年份的供水期的调度效果改进不明显。更多还原

【Abstract】 This paper evaluates currently practicing operation method of Qingjiang cascade reservoirs system with recently introduced HEC-ResSim model.Suitable operation rules for cascade reservoirs operation were derived using HEC-ResSim model.Considering 1955-2005 runoff records,three representative years(wet,normal and dry) were selected and 3-hour time interval simulation was carried out.A parallel simulation and comparative study was performed.Simulation results show that the HEC-ResSim model is significant over conventional method during wet and normal years and flooding seasons in all aspects and no significant difference in dry year and non-flooding seasons.It can be concluded that HEC-ResSim is a better simulation tool for Qingjiang cascade reservoirs operation than the conventional method.更多还原
