| 摘 要： | 严格推导了发生功率冲击时两区域互联系统联络线功率振荡的表达式。将发生功率扰动的系统分为扰动前、扰动瞬间和扰动后3个阶段，建立每个阶段的动态方程并推导运行点的变化。基于冲击功率的分配理论，推导了两区域互联系统在发生功率扰动后联络线功率的变化。扰动后，联络线功率呈现出区间振荡模式的衰减振荡，功率稳态值由两区域内发电机的总惯...

| Abstract: | The tie-line power oscillation of the two-area interconnected system due to power impacts is strictly derived.The power oscillation process caused by disturbance is divided into three stages,namely before,during and after the disturbance,and dynamic equation for each stage is established and the variation of the state point is derived.Based on the theory of distribution of impact powers in power systems,the tie-line power of the two-area system after power impacts is analysed.After the disturbance,the tie-l... |
