摘　　要：在分析了低频振荡产生原因的基础上,概括出低频振荡的分析方法具有基于系统实测信号和基于系统数学模型两大类,并对具体分析方法细化;总结交直流互联系统中低频振荡的抑制策略;重点对低频振荡的抑制及其关键技术问题研究现状进行介绍;最后对于低频振荡的后续热门研究问题做了展望。Based on the cause analysis for the occurring of low frequency oscillation, the analysis methods of low frequency os- cillation is concluded, which has two kinds, that is, based on the system measured signal and based on the system mathematical model separately, and the concrete analysis methods is refined. The strategies used in suppressing the low frequency oscillation in AC - DC interconnected system are summarized, and then the current states of the key problems about suppressing the low frequency oscillation are introduced in detail. Finally, the prospects are carried out on the follow - up hot researches of low frequency oscillation.
