HVDC - High Voltage Direct Current Power Transmission power can be supplied through the capacitor bank, synchronous condenser, or a suitable generating station locate near the converter. In the case of line commutated converter, the reactive power required is between 40-60% of its power rating. This demand can be reduced by converter transformer having a sufficient range of on-load tap changers.
