HVDC shunt tap based on series-input parallel-output DC-AC multi-module VSCs with DC voltages balancing
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Conventionally, tapping-off a small amount of power from an HVDC transmission line to a three-phase local network can be achieved using a DC-to-AC voltage source converter (VSC) followed by a step down transformer. In order ...
A grid-connected HVDC shunt tap based on series-input parallel-output DC-AC multi-module 2-level voltage source converters
(

, 2015 , Conference Paper)
Tapping-off a small amount of power from an HVDC transmission line to a three-phase local grid can be achieved by using shunt or series HVDC taps. This paper proposes a new grid-connected HVDC shunt tap. The proposed tap ...
