摘要
电力系统中持续的周期性小扰动可能引起联络线的大幅度强迫功率振荡。本文通过特征分析方法，阐明了电力系统强迫功率振荡的机理，指出了这类强迫功率振荡与负阻尼低额振荡的不同，并介绍了１９９４年４月２６日南方互联电力系统“４．２６”事故的仿真结果。
The large forcedpower oscillation in tieline may be caused by the sustained periodical smalldisturbance in power system. Using eigen analysismethod,the mechanism of the forced power oscillationin power system is expounded and the difference be-tween forced power oscillation and low frequency oscil-lation due to negative damping is pointed out in thispaper.The simulation result of a forced power oscilla-tion fault in South China interconnected power systemis presented.
