本数据集基于三峡-葛洲坝梯级水利枢纽调度运行资料，通过对三峡水库计算出库流量过程、小溪塔水文站实测流量过程、葛洲坝水库计算入库流量过程和计算出库流量过程进行水量平衡分析，对葛洲坝1号至21号机组进行基于栅前水位、时段出力的引用流量计算方法进行改进，计算方法由基于入库流量-水头损失曲线改为基于单机流量-水头损失曲线，显著降低了由于水头计算偏小导致的流量计量误差，以梯级水库上下游水量平衡为目标，实现了葛洲坝各机组发电流量的物理一致性修正，得到了该葛洲坝水库电站运行数据集，为水电站精准精细调度运行提供了数据支撑。
\n本数据集共5个sheet文件，分别为各机组发电流量数据（单位：m³/s）、机组毛水头数据（单位：m）、改造曲线计算发电流量结果数据（单位：m³/s）、修正水头损失后计算发电流量结果数据（单位：m³/s）、修正水头损失结果数据（单位：m），表头中，0F为0号机组即电源机组，1F~21F为1号至21号机组序号。梯调改造曲线：三峡梯调中心提供的葛洲坝机组增容改造后的机组出力-水头-流量特性曲线。", "ds_source": "

", "ds_ref_way": "", "ds_abstract": "This dataset is based on the dispatch and operation data of the Three Gorges and Gezhouba Cascade Water Conservancy Project. Through water balance analysis of the calculation of outflow flow from the Three Gorges Reservoir, the measured flow process from the Xiaoxita Hydrological Station, the calculation of inflow flow from the Gezhouba Reservoir and the calculation of outflow flow from the Gezhouba Reservoir, the calculation method of quoted flow based on the water level in front of the gate and the output of the period is improved. The calculation method has been changed from being based on the inflow flow-head loss curve to being based on the single unit flow-head loss curve, which has significantly reduced the flow measurement error caused by the small head calculation. Aiming at the balance of upstream and downstream water volume in cascade reservoirs, each Gezhouba unit has been achieved. The physical consistency correction of the power generation flow has obtained the Gezhouba Reservoir Power Station operation data set, which provides data support for accurate and precise dispatch and operation of the hydropower station.
\r\nThis dataset has a total of 5 sheet files, which are respectively power generation flow data of each unit (unit: m³/s), unit gross head data (unit: m), power generation flow calculation result data of transformation curve (unit: m ³/s), power generation flow calculation result data after correcting head loss (unit: m³/s), and corrected head loss result data (unit: m). In the header, 0F refers to Unit 0, i.e. power supply unit, and 1F-21F refers to the serial numbers of Units 1 to 21.
