Abstract  Combined with the phase conversion failure and power fluctuation in the operation of a special high voltage DC transmission project, through the introduction of the phase conversion failure Amin function of the DC control protection software program, the fault waveform on the scene was analyzed and the cause of the fault was analyzed. According to the actual operation situation of the site, the suggestions of corrective measures are put forward to ensure the safe and stable operation of the UHVDC transmission system.
Key wordsAmin function      phase change failed      arc corner      valve control
