(一) 概述水电站参数选择(包括正常蓄水位、死水位和装机容量的选择)涉及面很广,澜沧江基本上可以仅考虑水能的开发利用,但它仍然是一个相当复杂的问题。随着正常蓄水位的提高,水电站的兴利库容、保证出力、装机容量和多年平均发电量均将增加,但是大坝等水工建筑物造价和水库淹没损失亦相应增加,而且水库规模愈大,施工期愈长,发挥效益也愈晚。因此,通过系统分析可以求出一个最有利的方案。同理,在一定
(I) Overview Hydropower station parameter selection (including the normal water level, dead water level and the choice of installed capacity) involves a wide range of Lancang River basically only consider the development and utilization of water energy, but it is still a very complex issue. With the improvement of normal water storage level, the capacity of hydropower stations will be increased and the installed capacity and average power generation capacity will increase over the years. However, the cost of hydraulic structures such as dams and reservoir inundation losses also increase correspondingly, and the larger the scale of reservoirs Large, the longer the construction period, the more effective it is. Therefore, one of the most advantageous solutions can be found through systematic analysis. Similarly, at a certain
