微型水电是指容量在100千瓦以下的水电。本文通过对已建成投产的电站的分析,对美国微型水电的经济效益、存在问题以及发展趋势进行了探讨。微型水电对国家能源生产虽不可能做出较大的贡献,但它却能让能源开发者从国营系统中单独分出来,以致使能源生产更加分散、灵活,更有保证,为分担国家能源供应做出一定的贡献。据统计,在美国一个中等家庭用户每月平均耗电量约为1,000千瓦小时,平均峰荷每户约2.5千瓦。一个100千瓦的微型水电站(考虑50%的电站容量因数)将能满足40个家庭用户。若采
Micro-hydropower refers to hydropower with capacity below 100 kilowatts. Based on the analysis of power stations that have been put into operation, this paper discusses the economic benefits, existing problems and development trends of the US micro-hydropower. Although it is impossible for national hydropower to make a great contribution, micro hydropower can separate energy developers from the state-owned system, making energy production more decentralized, flexible and more assured. In order to share the national energy supply Make some contribution According to statistics, an average household user in the United States consumes an average of about 1,000 kilowatt-hours per month with an average peak load of about 2.5 kilowatts per household. A 100-kilowatt micro-hydro power station (considering 50% capacity factor) will satisfy 40 home users. If mining
