新中国成立以来,随着社会主义建设事业的发展,小水电建设发展很快,已经成为地方经济特别是山区经济的支柱产业。但是,早期兴建的小水电站由于水文资料不足,规划设计不够合理,部分水电站机电设备选型不当,或调节性能差,弃水多,或利用小时数少,闲置容量多。这些电站通过技术改造挖掘潜力增加效益的可能性很大。现就江西省定南县小水电站现状进行分析,提出一些扩建增容、挖掘潜力增加效益的技改措施。 Since the founding of new China, with the development of socialist construction, the construction of small hydropower has developed rapidly and has become the pillar industry of local economy, especially in mountainous areas. However, the early construction of small hydropower stations due to inadequate hydrological data, planning and design is not reasonable enough, some of the hydropower station mechanical and electrical equipment improper selection, or poor regulation performance, abandoned more water, or less hours of use, idle capacity and more. There is a good chance that these plants will increase their profitability through technological innovation. Now on the status of small hydropower stations in Jiangxi Province Dingnan analysis, put forward some expansion capacity expansion, mining potential to increase efficiency of technical measures.
