Abstract:

For Jinan-Xuzhou part of 1 000 kV UHV Ximeng-Nanjing project, the transposition tower type is recommended of 1 000 kV UHV AC double-circuit transmission lines on same tower, by the analysis of technical and economic comparison, and by referring the research achievements and operating experience of domestic 750 kV and 500 kV double-circuit transmission lines on same tower. The research results in the paper can be applied to engineering design.
