Based on the port - controlled Hamilton with dissipation ( PCHD) model,a new L2 - gain repetitive control strategy of voltage sourced converter based high voltage direct current ( VSC - HVDC) system is proposed. In the theory,the converter model of VSC - HVDC is equivalent to a dissipative passive system,and according to different control modes of VSC - HVDC, the reference currents in the corresponding dq - axis are determined. On the basis,L2 - gain repetitive controller is designed to trace the reference currents and suppress the external disturbances. The simulation results verify the validity of the proposed control strategy.
