According to the feature of distribution network structure, a practical short circuit calculation method based on fault current compensation and actual phase sequence presentation is put forward. This method needs not to determine the three sequence networks according to the kinds of faults, it can calculate various kinds of short circuit currents in symmetrical and unsymmetrical distribution network, the calculation process is simple and easy to implement in computer. Results of calculation instances show that this algorithm is reliable and efficient in the calculation of short circuit current in radial distribution network.
