| 摘 要： | 提出了基于完整的模态分析技术的交直流系统电压稳定性分析方法。根据交直流系统的特点,采用简便的牛顿拉夫逊法计算交直流系统潮流解,形成雅克比矩阵。运用完整的模态分析技术的原理,得到交直流系统各个负荷母线和发电机母线的参与因子。以参与因子为依据,得出交直流系统的关键负荷母线、关键发电机和最容易电压失稳区域。通过IEEE14节点系统算例验证了所提出的模态分析方法的有效性。

| Abstract: | A complete modal analysis technique is suggested to analyze voltage stability of AC/DC system. According to the characteristics of AC/DC system, using a simple method of calculating the flow of AC/DC system which based on a Newton Raphson to form Jacobian matrix. Using the principle of the complete modal analysis techniques, the Participation fators of each load bus and generator bus are obtained. According to the Participation fators, the critical load bus, the critical generator and the region of the most likely to lose voltage stability are found. The simulation results of IEEE-14 system demonstrate that the proposed modal analysis method is effective. |
