英文摘要：

In view of the large computational error of the existing non iterative port compensation method and the large computational load of the iterative port compensation method, an improved port compensation algorithm is proposed. To make full use of the radial structure of distribution network, the back/forward sweep method is used to solve the open voltage of the fault port, the new fault port impedance matrix is used simultaneously which consider the influence of parallel branches. It not only improves the calculation speed, but also ensures the calculation accuracy. The method is tested by an example and compared with the traditional algorithm. The feasibility, validity and superiority of the algorithm are proved.
