Abstract :
Operation of HVDC converters under HVDC pole voltage imbalances is analysed. Asymmetrical HVDC pole current injection is achieved by directing current to the ground return path through a device installed in the AC side of the converter. Several operation modes, including asymmetric monopole, are presented and their sizing requirements are discussed.
