This paper analyzes the influence of voltage amplitude reduction, zero-crossing displacement, and volt-age waveform distortion on the commutation process based on the phenomenon of commutation failure in HVDC transmission system and its principles. . Commutation failures in high-voltage direct current (HVDC) transmission systems often occur within inverter stations, posing challenges to the safe and consistent operation of HVDC transmission projects. In the Yangtze River Delta, an AC/DC hybrid power grid exists. . Abstract: Commutation failure is a common fault for line-commutated converters in the inverter.
