Transmission of power through High Voltage Alternating Current (HVAC) Transmission lines results in power losses in the transmission line, higher the length of transmission line higher the losses, furthermore cost of transmission line also increases with length. In order to maintain the voltage within the limits, reactive power also need to be transmitted over the same line which again increases the power losses. In order to overcometheabove problems, High Voltage Direct Current (HVDC) is preferred to transmit the power when the distance of transmission is above 500kM, which requires only one conductor for Monopolar Link and ground acts as return conductor. The converters used for conversion of power from ac to dc produce harmonics, which can be handled with the filters. In the proposed work a 12-pulse HVDC converterwith Hybrid Active DC Filter (HADF) consisting of 100 MVAR Shunt Passive Filter and Shunt Active DC Power Filtercontrolled by fuzzy logicis designed and simulated in MATLAB/Simulink, Shunt Active DC Power Filter handled the higher order harmonics and compensated the remaining reactive power in addition to passive filters.
