摘　　要：一种由Ｎ个相同发电机组成的规则系统被考虑用来揭示电力系统振荡的一般规律。规则系统的特征值分成两类：类型一对应系统中发电机的整体运动，这些特征值与单机供一负荷的特征值相同。类型二对应发电机的相对运动，这些特征值与单机对无穷大母线的特征值相似。实际系统可以考虑为规则系统的扰动情况。扰动使特征值不再重叠一致而是分散在复平面上。一个两区域系统被用于区域振荡研究。特征值分类原则解释了单机对无穷大母线模型用于多机系统控制的有效性。ＰＳＳ被考虑用于区域振荡控制。o reveal the common regularity of power system oscillations , a regular system ,consisting of n machines of equal rating and equal design , is considere The eigenvalues of the regular system divide into two classes :Class one corresponds to the unitary motion of the machines in the system and these eigenvalues are the same as that of one machine feeding a load ,class two corresponds to the relative motion of the machines with respect to each other and these eigenvalues are similar as that of one machine against an infinite bus,A real power system can be considered as a disturbed case of the regular system. The disturbance hasthe effect that the eigenvalues do not coincide but spread.A two-area system is constructed for the investi-gation of inter-area modes,It is explained by eigenvalue classification principle : it is correct in theory to use the model of one machine against an Infinite bus in multimachine system control.PSSs are considered in inter-area oscillation control.
