临安县地处天目山压,可开发利用水力资源约11万千瓦。在六十年代,当全县架通了大电网后,早期兴建的小水电因电能质量差而被废弃。用电依赖大电网,丰富的水资源未被开发利用。随着工农业生产的发展,全县用电量迅建增长,特别在七十年代后期出现了一年更甚一年的电力缺口,对生产造成威胁,对生活造成不便,人们复又重视对山区水资源的开发利用,从实效出发,在大电网下办起了小水电。其与早期小水电相比,有三个不同特点。即:
Lin’an County is located in the mountain pressure, the development and utilization of hydraulic resources of about 110,000 kilowatts. In the 1960s, when the county had a large power grid, small hydropower plants built earlier were abandoned because of poor power quality. Power-dependent large grids, abundant water resources have not been exploited. With the development of industrial and agricultural production, the county’s electricity consumption increased rapidly. Especially in the late 1970s, power shortages of one year or more occurred. This posed a threat to production and caused inconvenience to people’s lives. People paid more attention to mountainous areas Development and utilization of water resources, starting from the actual results, run a small hydropower under the power grid. Compared with the earlier SHP, there are three different characteristics. which is:
