Abstract: In allusion to the voltage abnormal fluctuation phenomenon taking place in Tian Guang DC transmission system, this paper combined with DC voltage transformer design to analyze the problem causes. The design defect of DC voltage transformer second divider is the main cause of system voltage abnormal fluctuation. The corresponding improved measures were raised. The actual operation shows that the improved measures effectively remove DC voltage transformer design defect of Tian Guang DC transmission system, solving the system DC voltage abnormal fluctuation with certain reference value for DC voltage transformer design and model selection.
         Key words: Tian Guang DC transmission system; DC voltage transformer; voltage fuctuation
