农村小水电增效扩容装机复核及机组选型

为确保增效扩容改造后水电站的发电、生态和社会效益更稳定发挥，优化水力发电机组运行组合，根据电站现存问题，结合考虑“引红济石”调水量后的径流水能计算成果，合理确定与五里峡水电站工程实际相匹配的装机容量和机型。工程实践应用表明，比选获得的技改方案，能较好匹配电站日常运行水能指标。机组装机容量和台数能适应径流丰、平、谷年来水量的灵活调节，水能利用率及转换效率得到有效提高，弃水量减少，达到预期良好的技改增容和节能降耗效果。 

Turbine Selection and Installation Review of Synergism and Capacity Enlarging for Rural Hydropower Stations

In order to ensure hydropower station has more stable development of generation，ecological and social benefits，and optimize transformed unit operation combination，based on analysis of existing problems and runoff water energy calculations after water transfer capacity by water diversion project form Hongyan River to Shitou Rvier，installed capacity and turbine type of Wulixia hydropower station were confirmed.Application showed that better technological transformation scheme obtained by comparison and selection could better match daily running hydropower indicators of power station.Capacity and numbers of unit had good adaptability to flexible adjustment of wet，normal and dry year water intake，water utilization and conversion efficiency had been comprehensively improved，and abandoned water had been reduced，which could achieve a good technical transformation effect.
