Tapping small amounts of power from HVDC transmission lines using parallel cascaded converters

摘要

Tapping small amounts of power from HVDC transmission lines for rural electrification, has been the desire of network planners, designers and researchers for many years. This work investigates a parallel-cascaded converter topology for tapping small amounts of power from HVDC transmission lines. Further the effect of the parallel tapping station on the main HVDC transmission link during start-up of the tapping station is displayed.
