本文报告了一种解决所有类型短路问题的统一方法的发展。基本方法是考虑故障条件——故障类型或故障类型的组合以及相关的线路中断——作为对故障前网络分支参数的修改。传统补偿方案的一种扩展，称为两步补偿方法，用于解释网络在故障时所经历的平衡和不平衡特性。根据修正的平衡和不平衡性质，利用短路问题的结构特性，特别是稀疏性，对修正进行分解，得到了计算效率高的求解方案。这种解决方法对于系统范围的研究特别有用，在这种研究中，在大型系统中，在一组特定故障位置上的特定故障条件被依次分析。所建议的方法的一个值得注意的特点是处理互助的自然方式。本文给出了应用该方法对包括2278总线网络在内的多个系统的各种故障情况进行研究的结果。
This paper reports on the development of a unified approach for the solution of all types of short circuit problems. The basic approach is to consider a fault condition -a fault type or combination of fault types and associated line outages -as modifications to the parameters of the branches of the prefault network. An extension, referred to as the two-step compensation method, of the conventional compensation scheme was developed to account for the balanced and unbalanced nature ofthe modifications that networks undergo when faulted. The computationally efficient solution scheme was derived by using a decomposition of the modifications accor'ding to their balanced and unbalanced nature and exploiting the structural properties of the short circuit problem, notably sparsity. The solution approach is particularly useful for system-wide studies, in which specified fault conditions at a set of specifiedJfault locations are analyzed sequentially, on large systems. A noteworthy feature of the proposed methodology is the natural manner in which mutuals are handled. Results of the application of this approach to investigate a variety of fault conditions on several systems, including a 2278 bus network, are presented.
