%X 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. This 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. Stepper dispatching transformation curve: The unit output-head-flow characteristic curve of Gezhouba unit after capacity expansion and transformation provided by the Three Gorges Stepper dispatching center.
