AC/DC filter capacitor devices for DC transmission projects are applied on the AC side or DC side of high-voltage DC transmission systems. AC filter capacitor devices are installed in the AC field of high-voltage DC transmission converter stations to filter harmonics generated by converter valves and compensate for the reactive power required for converter valve operation; DC filter capacitors are installed in the DC field of high-voltage DC transmission converter stations to filter harmonic components in DC line currents and prevent interference with nearby communication systems.
