| Abstract: | In this paper,the existing lightning strike protection problems of distributed hydropower grid are analyzed in terms of grid-connected hydropower lines,hydropower stations and customers,and the lightning strike risk composition and risk sharing differences between grid-connected hydropower lines and normal ones are presented.Then,the lightning strike risk index is proposed.Moreover,a lightning strike risk evaluation model for the power grid with distributed hydropower is established,which considers the ligh... |
