当前乡村小水电站存在的问题:一、淘汰率高。据统计在“六五”期间,我国乡村电站平均每年淘汰5000处以上,容量近8万千瓦。究其原因主要是: (1)自然淘汰高。乡村电站大部分为微型电站,使用年限仅10~20年。60~70年代建的电站均已到退役年限,再加上洪水毁坏、改建大站、水利规划变动等客观因素,更加快了报废速度。 (2)统计存在误差。60~70年代,国家对乡村电站是根据投产的千瓦数给予补助投资,因此,为
Current rural small hydropower problems: First, out of high rate. According to statistics, during the “65” period, China’s rural power plants eliminated an average of 5,000 or more per year and had a capacity of nearly 80,000 kilowatts. The main reason is: (1) high out of nature. Most rural power plants are miniature power plants with a useful life of only 10 to 20 years. 60-70 years of construction of power plants have been decommissioned years, coupled with flood damage, alterations to the station, changes in water conservancy planning and other objective factors, more quickly scrapped. (2) statistics error. From the 1960s to the 1970s, the state subsidized the rural power plants according to the kilowatts put into operation. Therefore,
