摘　　要：文章在对白龙江喜儿沟水电站水轮机出力进行研究的基础上,通过技术创新,对喜儿沟水电站弧门排漂孔进行了封堵,对经济效益进行了分析。结果表明:封堵后,抬高了喜儿沟水电站水库发电运行水位,降低了发电单位耗水率,提高了水资源利用率,达到了增发电量目的,为同类水电站经济运行提供了借鉴。The originally designed drift bleed hole in Xiergou Hydropower Station has lost its function.The radial gate drift bleed hole of Xiergou Hydropower Station is plugged,and the economic benefits are analyzed through technological innovation based on the research on the turbine output of Bailong River Xiergou Hydropower Station in the paper.The results show that the reservoir power generation operation water level of Xiergou Hydropower Station has been raised after the plugging,the unit water consumption rate of power generation has been reduced,and the utilization rate of water resources has been improved,and the purpose of generating more electricity has been achieved,and the paper provides reference for the economic operation of similar hydropower stations.
