摘　　要：本文通过对现有的微网故障定位矩阵算法的研究,提出一种可行的微网故障定位矩阵算法,同时作为微网保护的后备保护,不仅可以保护微网中的母线,还可以保护微网中的馈线及末端线路,适用于并网和孤岛两种运行方式。最后在PSCAD/EMTDC仿真软件上进行建模及故障仿真模拟,在Visual Basic软件上进行算法结果的可视化展示。Based on the research of the existing fault location matrix algorithm of the microgrid,this paper proposes a feasible fault location matrix algorithm of the microgrid.As the backup protection of microgrid protection,it can not only protect the buses in the microgrid,but also protect the feeders and terminal lines in the microgrid.It is suitable for two operation modes of the grid-connection and isolated island.Finally,modeling and fault simulation are carried out on PSCAD/EMTDC simulation software,and the algorithm results are visualized on Visual Basic software.
