The platform of 1 000 kV series compensation device is much larger than that of 500 kV on area, quality and installation height. Therefore it is of great importance to investigate the hoisting technology for platform of 1 000 kV series compensation device in detail. Concerning different plane layouts in field, three schemes for platform assembly on ground are proposed. In addition, three platform hoisting schemes are proposed by one crane, two or four cranes combined respectively, and compared from technical and economic view. The scheme by four cranes combined is applied in UHV DC test base, of which the effectiveness is verified.
