An investigation into series power tapping options of HVDC transmission lines

The first commercial success in HVDC transmission was made in 1954 and it has since become popular as attempts have also been made to tap energy from the HVDC line itself. This paper discusses technical issues that are related to series energy tapping options for HVDC lines, with possible solutions. The performance and behavior of four different design options for a 2 MW series tap are investigated through simulations. Results are presented with comparisons, highlighting the key characteristics of each design, as proof of concept and as well as to demonstrate that series power tapping from HVDC lines is viable.
