摘　　要：介绍了南澳多端柔性直流输电系统实际运行中发生的一起非常特殊的功率波动事件,从事件的现象出发,以故障录波图和控制保护系统说明书为依据,分析功率波动的内在原因,为今后分析处理类似的异常事件提供参考依据,并提出合适的改进措施以提高柔性直流输电系统的运行可靠性。One special power fluctuation event in practical operation of Nan’ao multi-terminal flexible high voltage direct current（HVDC）transmission system was introduced. Starting from phenomena of the event and on the basis of fault recor-ded waveform and specification of control protection system,internal reasons for power fluctuation were analyzed which might provide references for analyzing similar exceptional events in future. Suitable improvement measures were proposed to improve operational reliability of the flexible HVDC transmission system.
