摘要
采用网络等值法对带有复杂分支子馈线的配电系统进行可靠性评估 ,并提出一种基于新的分层结构的等值算法。该算法通过将网络元件和分支子馈线组合成节点和线路 2种集合元件 ,根据配电网实际拓扑结构 ,采用层状的数据结构描述节点集合元件和线路集合元件之间的拓扑关系 ,从而避免直接描述网络元件之间的复杂关系。并采用宽度优先搜索算法对其进行顺向和逆向遍历求解系统的可靠性指标。
This paper presents an application of network-equivalent-based approach to reliability assessment of distribution systems with feeders of complex subfeeders, and an equivalent algorithm is proposed based on a novel topological representation with hierarchical structure. This algorithm classifies all the components and lateral feeders in the network into node-type and line-type aggregated components. In accordance with physical topology structure of distribution system, the topological relationship of the network can be represented by hierarchical structure of the aggregated components to avoid direct description of complex relationship between components in the network. The reliability indexes are computed by forward and backward search of all the aggregated components according to breadth-first search method.
