随着小浪底水利枢纽主体工程的完工,6台发电机组陆续投入生产发电,机组冷却用水量将达到3000m3/h。虽然黄河北岸供水工程的设计供水量为5000m3/h,但由于截流后黄河改道、近年来黄河来水量减小、黄河携带泥沙淤积和供水滩地地下水长期开采等因素,原供水滩地的水文地质条件发生了很大变化,水源地的供水量能否满足机组发电要求是影响电站经济效益的一个重点。
With the completion of the main project of Xiaolangdi Multipurpose Dam Project, 6 generating units are gradually put into operation to generate electricity and the unit cooling water consumption will reach 3000m3 / h. Although the design water supply volume of the Yellow River water supply project is 5000m3 / h, due to the Yellow River diversion after the closure of the Yellow River, the decrease of water flow in the Yellow River in recent years, the sediment deposition in the Yellow River and the long-term exploitation of groundwater in the water supply beach, the hydrogeological conditions Great changes have taken place. Whether the water supply of water source can meet the power generation requirements of generating units is a key point that affects the economic benefits of power plants.
