Rural electrification using overhead HVDC transmission lines

Abstract

One of mankind’s greatest modern challenges is poverty alleviation. The provision of electricity can greatly assist in this regard. The tapping of small amounts of power from an HVDC transmission line represents a solution to this problem especially in rural areas. This paper analyses the dynamic characteristics of a parallel-cascaded tapping station. The results obtained clearly indicate that the parallel-cascaded tapping station proves to be a viable solution to tapping small amounts of power from an HVDC transmission line.

Input‐voltage and output‐current equalization of series‐in parallel‐out three‐phase multi‐module voltage source converter‐based high voltage direct current shunt tap

“…High voltage direct current (HVDC) transmission is used to transfer bulk amount of power efficiently over long distance. Shunt and series HVDC taps are the possible options to tap small amount of transferred power to feed a local network near to the HVDC lines 1–3 . The small tapping station should satisfy some conditions such as low cost, negligible impact of the main DC‐link and no clashes between tap and DC‐link controllers 4 .…”

“…Shunt and series HVDC taps are the possible options to tap small amount of transferred power to feed a local network near to the HVDC lines. [1][2][3] The small tapping station should satisfy some conditions such as low cost, negligible impact of the main DC-link and no clashes between tap and DC-link controllers. 4 As mentioned before, there are two possible options to tap small amount of power from the power transferred through the HVDC line, namely, parallel-tap [5][6][7][8][9][10] and series-tap.…”
