| Abstract: | This paper analyzes the necessity of adopting higher voltage level above 330kV for northwest power system from six aspects.and puts forward three schemes on which economic comparison and calculation are conducted. Based on the analysis of main factors that influence the selection of higher voltage level, decision index system and support system for transmission voltage have been set up. The voltnge level decision support system has been applied to evaluate above-mentioned three schemes, the results show that AC 750kV is the best one based on comprehensive techniflue and economic comparison. At last, according to the overseas experience of higher voltage level selection, the development situation of technology and equiprnent of extra - high voltage transmission and transformation at home and abroad. the reality of adopting750kV as higher voltage level above 33okV for northwest power system has been analyzed. |
