Abstract: 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.
