| Abstract: | The construction of higher voltage level power transmission grid is an inexorable trend of northwest power system development. This paper describes the effect of inter-regional interconnection upon the selection of higher voltage level.the problem of voltage level serialization across the country, reasonable disposition of voltage levels, unfavorable effects of closed related voltage level upon system operation, as well as the effect of grid structure upon voltage selection. It also puts forward the priority of adopting 75OkV higher voltage level in northwest power system. |
