摘    要:根据配电网短路电流计算的基本原理,按面向对象技术设计并实现了配电网拓扑分析和短路电流计算。短路电流计算采用基于叠加原理的前推回推法,拓扑分析则根据前推回推法的特点采用支路分层的方法,两者结合有效地保证了算法的效率。在实现中,按面向对象技术设计了支路、节点、层和馈线类,并在这些类的基础上实现了拓扑分析和短路电流计算。利用33节点、123节点和292节点系统对实现的算法软件进行了性能测试,结果表明,算法软件具有很高的效率。

关 键 词:网络拓扑  短路  电流计算  配电网  面向对象技术

Abstract:According to the principle of short circuit calculation for distribution network, the distribution network topology analysis and short circuit calculation are designed and implemented in this paper, and the implementation is based on the object-oriented technique. The backward/forward method based on the superposition theorem is adopted in short circuit calculation, and the branch layering method is used in the topology analysis. The combination of two methods guarantees the efficiency of short circuit calculation algorithm. Moreover, the object classes based on the object-oriented technique are designed to implement the short circuit calculation. The performance test results of 33 nodes system and 123 nodes system and 292 nodes system are also offered in this paper, and the results indicate that the realized program has high efficiency.
Keywords:distribution system  topology analysis  short circuit calculation  object  oriented technique
