Calculation and graphical display of surge current due to closing loop based on dispatching and distribution integration loop automatic search and automatic layout drawing

The close-loop operation is the important method of adjustment operating mode in medium voltage power distribution network. This paper uses the loop automatic search method for fast and accurate identification of close loop path, and provides a simplified model method to calculate the surge current due to closing loop based on the Close-loop transient process theoretical analysis. Then show the graph of Close-loop network by automatic layout mapping technology to provide auxiliary decision of closing loop operation.
