滩坑水电站降低河床底高程发电增效的实践

Benefit increase by lowering river bed at Tankeng hydropower station

滩坑水电站利用降低下游河道河床底高程的手段,减少发电耗水率,取得了良好的增效效果,电站的经济效益指标得到了提升。经分析,该增效措施也不会对水轮机造成不利影响,是水电站节能增效的成功实践。

By lowering river bed downstream, the water consumption rate was decreased and the power generation increased. Further, the analysis showed that the lower river bed would not exert adverse effect on generation units.
