外文摘要：Aiming at the structure characteristics of middling and lower voltage distribution network， this article advances a new algorithm for its short circuit calculation。 Algorithm translates complex grid with several loops to some dendriform subnets with substitution theorem， and acquires voltage matrix equation by Thevenin's equivalent on power paths， calculates the current of broken node sequentially。The algorithm overcomes the troubles that take place in node matrix algorithm such as great spending for resistance， low agility of system reconstruct， and extents the localization to loop in direct analyzing algorithm。 Last examples prove its availability， good efficiency and precision。
