Websituations in which conversion from HVAC to high-voltage direct current (HVDC) is the least-cost strategy to increase the capacity of the corridor. If restricted to the existing right-of-way (ROW), we find DC conversion to be the least-cost, and in some cases the only, option for distances of >200 km or for increases of >50% capacity. WebThe HVAC transmission requires a minimum of 3 conductors for 3-phase power transmission while in case of HVDC that can utilize the earth as the return path can use only 1 conductor for mono-polar transmission or 2 conductors for a bipolar transmission. It substantially decreases the overall cost of the transmission.
