电网多区域多端口参数等值方法及其应用

根据变结构网络中拓扑结构的变化可以用添加等值支路来模拟的特点,通过添加支路模拟线路开断并对原网络节点阻抗矩阵进行修正,结合多端口戴维南等值及通过节点导纳矩阵形成等值支路的方法,提出了一种多区域多端口等值的快速求解方法,并给出算例验证和在整定计算软件中的实际应用。

Application of Calculation Method for Multi-region and Multi-port Parameter Equivalents in Power Grid

Since the topological changes of variable structure network can be simulated by adding equivalent branches,the line outage is simulated and the node impedance matrix is modified combined with the method of multi-port Thevenin equivalents and forming the equivalent branches with node admittance matrix,this paper presents a fast solution of multi-region and multi-port equivalents,the example for the verification and the application in setting calculation software.
