| 摘 要： | 在分析传统的支路追加法形成节点阻抗矩阵缺陷的基础上,提出了虚拟接地支路和连支度的概念,采用增加虚拟接地支路的方法使电网节点和支路的追加顺序不受任何条件的约束,并通过节点对连支度的比较确定电网节点和支路追加顺序,从而显著降低了形成节点阻抗矩阵的计算量。最后用实例验证了该方法的有效性。 |

| Abstract: | On the basis of analyzing the defects in building Z-matrix by traditional adding branches method, the concepts of invented grounded-branch and connected-branches dimension are proposed. Using adding invented grounded- branch, the order of adding nodes and branches of power network is no longer restrained by any conditions, and the order of adding nodes and branches is determined by comparing the nodes with connected-branches dimension, therefore the calculation amount of building Z-matrix is evidently reduced. The effectiveness of the proposed method is verified by the results of practical examples. |
| Keywords: | bus impedance matrix invented grounded- branches adding branches method connected-branches dimension |
