3) During bad weather conditions, the corona loss and radio interference are lower for a HVDC line co mpared to that in an AC line of same voltage and same conductor size. 4) Due to the absence of inductance in DC, an HVDC line offers better voltage regulation. Also, HVDC offers greater controllability compared to HVAC.

This is a two part series on HVDC Transmission. Part 1 of this series looked at specific applications where HVDC Transmission excels, other applications that may not be as suitable, and the geographic area in the U.S. Grid where they have, and will continue to be used extensively. Part 1 also looked at the technology used to implement HVDC lines.

The choice between using HVDC or HVAC is usually justified by economics, i.e., decision makers look at costs versus benefits. For example, system stability can be much better with HVDC, and more power can be transferred over the same ROW than HVAC. In general, HVDC is more cost‐competitive than

HVDC Disadvantages HVDC is generally less reliable and has lower availability than HVAC. Mainly due to the extra conversion equipment and maintenance difficulty.
