Abstract Basing on the achievement that the level equivalent algorithm for short circuit calculation in dendriform network, this article will expand the application scope of the algorithm to common networks with loops. In the algorithm, complex grid is translated to some dendriform subnets with substitution theorem, and then the voltage matrix equation will be acquired by Thevenin's equivalent on power paths, the current of broken node will be calculated sequentially. The algorithm overcomes the troubles that took place in node matrix algorithm such as great spending for resistance, low agility of system reconstruct , and extent the localization to loop in direct analyzing algorithm. Its availability, good efficiency and precision are proved in the last examples.

Key words： Short-circuit calculation radial structure level equivalent loop substitution theorem compliexity analysis
