[Abstract]:This paper analyzes the domestic and international research status of the dynamic characteristics of tubular hydropower stations, as well as the economic operation of the plant and the distribution of the active power load of the hydropower stations at home and abroad. This paper points out the problems existing in the power generation efficiency of hydropower stations and the deficiency of the active power load distribution method adopted at present.
