黄河上游水电具有廉价电能、扩大装机投资小和高原水库蓄能的优势。发挥这些优势,不但是西北地区经济发展的支柱;而且还可担负华北的尖峰重担;并能提高华中和西南电网水电的保证出力,把部份季节性电量转化为保证电量,又可使华中向华东电网多输送些保证电量;因而对全国七大电网中的五大电网能发挥作用。 Hydropower in the upper reaches of the Yellow River has the advantages of low-cost electric power, small installed capacity expansion and high-altitude reservoir storage. To play these advantages, not only is the pillars of economic development in Northwest China; but also can bear the spike in North China burden; and can improve hydropower in central and southwestern power grid to ensure that some of the seasonal power into electricity to ensure that they can make Huazhong East China Power Transmission more to ensure that some electricity; thus the country’s seven major power grid in the five major grid can play a role.
