摘要
提出了一种以开关作为支路,以开关两端的馈线作为节点的节点-支路关联矩阵描述配电网馈线拓扑结构,并给出了基于这种关联矩阵的故障区域定位新算法。通过算例证明该算法是正确的。计算中无须进行矩阵计算和判据矩阵的规格化处理,大大减少了故障区域判据矩阵的维数,提高了计算速度,同时对于支路末梢的故障区域也能正确判断。
Node-branch incident matrix'is introduced to describe the topology of distribution fee-der net,which regards breakers as branches and lines connecting the breakers as nodes.A new al-gorithm based on the incident matrix is presented to locate the fault section,which is proved correct by example calculations.The matrix calculation and the formatting of judgement matrix are not necessary,the dimension of fault section judgement matrix is hence reduced and the cal-culation speed enhanced.The fault section at feeder end can be specified correctly as well.
