| 摘 要： | 三峡水利枢纽分设左右两岸厂房，单机容量７００ＭＷ，正常蓄水位１７５．００ｍ在厂房进水口研究上，长科院和清华大学都进行了各处水工模型试验，研究了边壁压强分布，水头损失和进口流态，双孔方案水头损失，机组运行稳定性等方面较单孔有利，无论单或双孔，经优化后，水头损失都减少了约１５ｃｍ，年发电量约增加１．５万ｋＷ．ｈ，具有巨大的经济效益。

| Abstract: | A powerhouse will be arranged either side of the spillway for the Three Gorges Projeet. Each unit will hsve an installed capacity of 700 MW. The normal reser-voir level will be 175. 00 m. The wall pressure distribution, head loss and flow condit-ions in front of intakes were studied by Yangtze River Scientific Research lnstitute and Tsinghua University, through extensive hydraulic model tests. The double - bay sche-me is more favourable than the single - bay one with reapect to the head loss, operation stability, etc. But through optimizing, whether for the sing-bay scheme or the double - bay one, the yearly generation may be increased by some 15 MW. h, showing its hu-ge economic benefits. |
