| 摘 要： | 本文建立了ZIP负荷和感应电动机负荷静态模型的综合负荷模型,并推导了计入综合负荷模型后的潮流雅克比矩阵。并在改进奇异值分解法的基础上,利用弱节点判断指标,分析了不同负荷模型对系统弱节点的影响。通过对IEEE30节点系统进行仿真计算,取得了满意的计算结果,从而验证了本文建立综合负荷模型及相应弱节点指标的正确性和可行性。 |
| 关 键 词： | 改进的奇异值分解法 综合负荷模型 薄弱节点 电压稳定 |

| Abstract: | The paper built a combined load model of ZIP load and induction motor load static models, and deduced the power flow Jacobin matrix included combined load model. At the base of improved singular value decomposition, the thesis also analyzed different load model＇s influence on the system＇s weak nodes, with weak nodes criterion. By the simulation of IEEE30 node system, the paper get a satisfactory results, and then verified the correctness and practicality of combined load model and its relevant weak node index. |
| Keywords: | modified singular value decomposition composite load model weak node voltage stability |
