Sediment Avoidance Operation Techniques and Measures for Run-of-River Hydropower Plants in High-Sediment Rivers during Flood Season

对多泥沙河流的径流式水电站汛期运行、排沙避沙技术进行了论述,通过电站来水含沙情况调查分析,提出一整套冲沙闸合理排泄、沉砂池引水渠清理、避开特定时段发电等运行技术及实施措施,有效减少泥沙淤积、机组过流泥沙含量,保障汛期电站的安全运行及发电指标。

This paper discusses the operationduring the flood season and sediment avoidance operation techniques of run-of-river hydropower stations in sediment-laden rivers.Through investigation and analysis of the sediment concentration in the incoming water of the power station,a complete set of operation technologies and implementation measures such as reasonable discharge of sediment sluices,cleaning of the diversion channel of the sedimentation tank,and avoiding specific periods of power generation are proposed.These measures effectively reduce sediment deposition and the sediment content of the unit flow,ensuring the safe operation and power generation indicators of the power station during the flood season.
