1 10 Largest HVDC Transmission Lines In The World by Shayan Amani ID : 9008463 Student of S.U.T Prof. Dr. A.Hadji Zadeh Winter 2014

2 In this presentation, 10 most powerful HVDC (High Voltage Direct Current) transmission lines constructed in the world, sorted respectively with consideration of power rated of the lines. Only finished and in operation projects ranked here. dismantled lines, abandoned and in construction projects not qualified for this list.

3 HVDC projects for long-distance transmission have two (or rarely, more) converter stations and a transmission line interconnecting them. Generally overhead lines are used for interconnection, but an important class of HVDC projects use submarine power cables. A back-to-back station has no transmission line and connects two AC grids at different frequencies or phase counts.
