摘　　要：灯泡贯流式机组在我国低水头电站中运用广泛,因其结构复杂,超设计水头范围运行存在较大安全隐患。近年来,受下游挖沙、航道整治等河势演变影响,沅江、湘江、赣江部分低水头电站水头超高现象频发,严重影响机组运行安全及梯级效益发挥。以沅水桃源水电站为例,通过问题剖析、对策分析、方案比选、影响评价等步骤探索解决该类问题的技术路径。The bulb turbine is widely used in low-head hydropower stations in China.Due to their complex structure,there are great security risks in the operation beyond the design head range.In recent years,affected by the evolution of river bed such as downstream sand dredging and waterway improvement,some low-head hydropower stations on the Yuanjiang,Xiangjiang and Ganjiang rivers have experienced excessively high head in power generation,which seriously affects the safety of unit operation and the performance of cascade benefits.Taking Taoyuan Hydropower Station on Yuanshui River as an example,the technical path to solve such problems is explored through the steps of problem analysis,countermeasure analysis,scheme comparison,and impact assessment.
