时段差异性对梯级水库蓄能调度方式的影响

Analysis of the Influence of Stage Scale on the Energy Storage Dispatching Mode of Cascade Reservoirs

以长江流域溪洛渡-向家坝-三峡梯级水库为例,通过设置7种不同调度时段长度,探究了调度时段尺度差异对梯级蓄能调度图调度结果的影响规律,并从不同调度时段的模拟结果分析了成因,进一步量化了不同调度时段长度对梯级水库发电调度结果的影响。在此基础上模拟计算和统计分析了三峡水电站更短的调度时间尺度,提出了针对水电站制作计划与实际调度中时段差异性问题的应对措施,为水电站实际生产调度提供了有力的参考和借鉴。

Taking the"Xiluodu-Xiangjiaba-Three Gorges"cascade reservoirs in the Yangtze River Basin as an example,this paper studied the influence law of length difference of operation stage on the final operation results of energy storage operation chart by setting seven different lengths of operation stage.The reason for the influence law is further analyzed from the simulation operation results of reservoir under different operation stages,and the influence degree of different operation stages on the operation results of cascade reservoirs is quantified.In addition,in view of the inconsistency between the long operation stage in making the plan and the short operation stage in implementing the plan,this paper puts forward the corresponding countermeasures through the simulation calculation and statistical analysis on the shorter operation stages,which can provide a strong reference for the actual production of hydropower stations.
