School of Machine and Electric Engineering, Shandong Science and T echnology University, T ai an 271019, China; 2. School of Electric Engineering, Shandong University, Ji nan 250061, China) Abstract: This paper presents an automatic loop node determination and fundamental circle algorithm to avoid manual deciding in weakly meshed distribution network. T he start or end node of link obtained by breadthfirst search is loop node. T hen it is divided into two nodes. T he voltage difference between thetwo nodes is little. So it can improve convergence efficiency and reduce the iteration number to some extent. T he method marks the child node of each node in the process of breadthfirst search. Then the meth od can rapidly search the tree branches from the two splitting node to root node. T hus the fundamental circle is automatically achieved. Different distributio
