The Remote Power Feeding System for Submarine Cable Based on Power Branching Unit

Through analyzing the bottleneck existed in the remote power feeding system for multi-submarine cable,a design scheme based on submarine power branching unit is studied and discussed.The structure of that branching unit is presented emphatically;the working principle of it is analyzed in detail.It is simulated and analyzed using PSPICE software.The simulation data verify the correctness of the theoretical analysis,which shows the branching unit an meet the needs of remote power feeding system for submarine cable.
