| 摘 要： | 结合电力系统自身的特点,考虑了负荷的三种类型,将恒功率、恒阻抗和恒电流三种类型结合起来,修改传统的模态分析矩阵,并在矩阵中增加了发电机无功部分,快速准确地得出该模式下的关键节点和关键发电机.与传统的模态分析方法相比,该方法准确性好,计算速度快,适用于在线分析.本文采用了IEEE 39母线系统进行了仿真计算,结果证明了该方法的有效性.

| Abstract: | Three load models including constant power load,constant impedance load and constant current load are considered. Through amending traditional modal Jacobian and adding generator reactive power variation,key nodes and key generators can be acquired fast and accurately. Comparing with traditional modal analysis,the method is accuracy and computing speed is fast. It is fit for on-line analysis. IEEE 39-bus system simulation shows the validity of this method. |
