摘　　要：基于等效电气距离理论,分析了电网发生强迫功率振荡时的时空传播特性,指出系统节点离强迫振荡扰动源等效电气距离越近,频率变化量扰动机电波越先到达该节点。利用PSD-BPA软件对WSCC 3机9节点系统进行仿真分析,结果证明了上述结论的正确性。Based on the theory of equivalent electrical distance, this paper analyzes the time-space propa- gation characteristics of forced power oscillation and points out that the disturbance electromechanical waves of frequency variation always get earlier to the buses of closer equivalent electrical distance from the disturbance source. A simulation for WSCC 3-generators-9-buses system in PSD-BPA is implemented to verity the validity of the above-mentioned conclusion.

关 键 词：等效电气距离 强迫功率振荡 扰动源 频率变化量
