This paper analyses the feasibility of converting the existing 400kV and 765 kV Double circuit AC Transmission line available in Indian scenario to HVDC line without altering the tower structure, line insulators and conductors. It has been observed that though line losses are more in HVDC system compared to AC Transmission line, there has been substantial increase in Net power transfer capability i.e. 2.84 times and 2.75 times increase in power transfer with +/-200kV HVDC and +/-400kV HVDC configuration respectively by using the existing conductors close to their thermal limits. Moreover, the benefits of all the advantages of HVDC are obtained by adapting this conversion.
