Design of Rapid Automatic Fault Location and Graphics Display Software System of Lines in Distribution Network

In view of the long fault localization time and fault clearance in mid-voltage power grid,a simple automatic and graphic positioning scheme of software system is proposed based on a combination of tree-like topological structure and the vector operations of monitoring nodes information for the mid-voltage power grid.The naming rules and vector information settings of the monitoring nodes in software is analyzed.The judge method in which the fault lines and line segment are most likely to occur is presented.And the result displayed by color in mapobject component is easily understood.On-site running proved that the above scheme is correct and feasible,speed of fault localization is fast,and the graphic display is accurate,and thus the system makes fault treatment easier and more convenient.
