小浪底电站建成后进行调峰运行时，坝址日内平均断流时间约为7．4h，小浪底──花园口河段工要取水口多年平均日内流量小于200m3／s的持续时间为8．6～2．9h，对本河段的引、提水工程引水将造成较严重的影响，也将影响花园口附近的水质。当小浪底充分调峰、西霞院反调节后，可以满足坝址至花园口河段的引水要求和花园口附近的水质要求，与小浪底承担强迫基荷相比，可使小浪底电站设计枯水年调峰工作容量增加153MW，多年平均增加峰荷和腰荷电量11．9亿kw·h。
Xiaolangdi Hydropower Station completed peak load operation, the dam site average flow-off time is about 7.4h, Xiaolangdi ─ ─ Huayuankou section to take water intake multi-year average daily flow less than 200m3 / s duration of 8.6 ~ 2.9h, the lead of this section, water diversion project will have a more serious impact on the water will also affect the water quality near Huayuankou. When Xiaolangdi full peak, Xixiayuan anti-regulation, you can meet the dam site to Huayuankou section of the water diversion requirements and Huayuankou near the water quality requirements, compared with Xiaolangdi commitment forced base load, Xiaolangdi power station design can be dry years Peak load capacity increased by 153MW, increasing peak load and waist load by 1.19 billion kw · h on average for many years.
