农村小型水电站大多兴建于上世纪六七十年代,装机一般为数十千瓦至数百千瓦,电能质量差、设计不合理、技术落后、机电设备陈旧老化。对这些电站投入较少资金进行技术改造后,较短时间内即可投入运行,对缓解当前电力供需矛盾和降低供电部门购电成本有较为积极的经济意义。 Most rural small-scale hydropower stations were built in the sixties and seventies of last century, installed capacity is generally tens of kilowatts to hundreds of kilowatts, poor power quality, design unreasonable, backward technology, mechanical and electrical equipment aging. Putting these funds into operation after a short period of time after investing less funds will have a positive economic significance in alleviating the current contradiction between supply and demand of electricity and reducing the cost of purchasing electricity in the power supply sector.
