摘要
将线路上短路点的电流向该线路端点等值转移，并综合应用线性网络特性、修正节点电流源与短路点列阻抗元的方法，导出了大型电力系统短路故障分块算法中互感或无互感线路上任意点故障计算的通用模型和算法，适用于定结构及变结构系统。
Based on the properties of linear network,a new generalized diakoptical modeland its algorithm are presented in the paper to calculate short circuit at the arbitrary location on anytransmission line of large-scale power systems,in which the proposed techniques of transferring faultport current,and modifying nodal current sources and column impedence elements, are appliedcomprekensively. The method given here is espocially efficient to calculate short circuit in piece-wisemethod for any mutually coupled cuts between subdivisions in the system with constant or variablestructures. And it is an important improvement for short-circuit current calculation.
