人类利用水能发电已有140年的历史了。开始是小型,以后逐渐进入中型,到了本世纪四十年代才出现了单机出力达10万千瓦的机组,七十年代后期又研究出了70万千瓦的大型机组。一些工业发达的国家,历史上最早也是以开发小型水电为主,经历一个漫长的时期才逐渐开发中型、大型,以至于当前的巨型水电站。因为小水电站的发电量小,不宜向远处输
Hydropower has been used by mankind for 140 years. The beginning is a small, then gradually into the medium, to the 40s of this century appeared only stand-alone output of 100000 kilowatts of units, the late seventies has developed a 700000 kilowatts of large units. Some industrially developed countries, the earliest in history, were also developing small-scale hydropower, and only after a long period of time did they gradually develop medium-sized and large-scale giant hydroelectric power stations. Because small hydropower generating capacity is small, should not be lost to the distance
