Abstract: A three-phase dynamic phasor (TPDP) model of High Voltage Direct Current (HVDC) systems was proposed. The proposed model could rapidly solve the dynamic characteristics of HVDC systems for AC system symmetrical and asymmetrical operating conditions. Switch functions model of converter was enhanced according to commutation process analysis of the converter. Due to the frequency characteristics analysis results, the TPDP model of HVDC systems with the converter, DC line and controller were established through dynamic phasor theory. Simulation results show that the proposed model is effective and acceptable..
