In this paper, the time requirements for the short-circuit calculation of distribution network using two different algorithms are compared. The first is the current summation and voltage correction algorithm (CSVC) that is commonly used for distribution networks, while another is a matrix algorithm commonly used for calculations in transmission networks. The time required for the calculation of three large, real, distribution networks, containing 1000, 5000 and 10000 nodes, respectively, were compared. The aim of this comparison was to examine the possibility of using a much more robust and extremely accurate matrix algorithm for the calculation of large-scale distribution networks affected by short-circuits.
