| Abstract: | Based on the analysis of the structure and characteristics of smart grid,it figures out the differences of the construction between relay protection of smart grid and that of traditional power system.Meanwhile,it elaborates the key technology of relay protection of smart grid,and raises a new way to implement the protection principle.Three problems are taken into account in detail,which include self-adjusting of protection setting,self-adjusting of protection function in accordance with operation mode and the impact of environmental condition on setting protection value. |
