This paper addresses a new approach for real-time short circuit analysis of radial and weakly meshed distribution networks. The approach works based on a well documented radial power flow study method, and uses a hybrid compensation method to account for loops, PV nodes, and fault currents simultaneously. The three-phase short circuit analysis, in its actual a-b-c phase representation, can be applied to balanced or unbalanced distribution systems. A distribution short circuit program which is developed based on this approach, is integrated with a three-phase power flow program to solve various types of single or simultaneous faults, including single-line to ground, three-line to ground, double-line to ground, line-to-line, and double three-line to ground faults. Results of the application of this approach to large-scale distribution networks are also reported in this paper.
