A three‐phase dynamic phasor (TPDP) model of high‐voltage direct current (HVDC) systems is proposed. The proposed TPDP model of HVDC systems can rapidly solve the dynamic characteristics of HVDC systems under the asymmetrical conditions of an alternating current system. The switch function model of the converter is enhanced according to commutation process analysis of the converter. Due to the frequency characteristics analysis results, the TPDP model of the HVDC systems including the converter, DC line, and controller are established through dynamic phasor theory. Simulation results show that the proposed model is effective and acceptable.
