基于乌江梯级水库年初低蓄能的调度运行安排

Scheduling and Operation Arrangement Based on Low Energy Storage of Wujiang Cascade Reservoirs at the Beginning of the Year

为了合理利用流域水力资源,提高梯级水电经济效益,乌江集控一直注重水电优化调度,在实践中逐步创建了年度运行方式建议、月度运行方式建议、周运行方式建议、日运行调度意图控制单。通过预测流域来水情况,结合梯级各电站设备实际情况和电网电量需求,在汛期和非汛期情况下,特制定了不同调度运行方式来达到乌江梯级运行最优的情况,因年初乌江梯级水库蓄能较低,面对年初低蓄能的情况,乌江梯级对年初非汛期的调度运行安排作出简要探讨。

In order to make rational use of hydropower resources in the basin and improve the economic benefits of cascade hydropower,Wujiang Central Control has always focused on optimizing hydropower scheduling.In practice,it has gradually created annual operation mode suggestions,monthly operation mode suggestions,weekly operation mode suggestions,and daily operation scheduling intention control forms.By predicting the inflow situation of the watershed and combining it with the actual equipment situation of each cascade power station and the electricity demand of the power grid,different scheduling and operation modes have been formulated to achieve the optimal operation of the Wujiang cascade during flood and non flood seasons.Due to the low energy storage of Wujiang Cascade Reservoir at the beginning of the year,a brief discussion was made on the scheduling and operation arrangements of Wujiang Cascade during the non flood season at the beginning of the year.
