摘要
综合采用修正节点电流源和列阻抗元素的方法,提出了变结构大型电力系统输电线路的带旁路支路和不带旁路支路双端电源等值模型,可快速得到系统变化后的模型等值参数,避免了惯用修正节点阻抗拒阵的大量运算和故障新增节点对线路模型节点阻抗拒阵的增广或修正,适用于线路正常和故障工况下的分析计算。
An equivalent model with double-end sources for transmission line of large-scale power sys-tem with variable structures is presented in this paper,which may be with a bypass branch or none.Thetechniques of modifying nodal current sources and column impedance elements are applied comprehensively,and equivalent parameters of the model can be obtained rapidly. And it can be used fOr calculating normalor fault conditions of transmission line and analyzing protective device performances.
