|Abstract: ||The variations of short-circuit capacities (SCC’s) along a feeder while a primary network is upgraded from original radial to normally closed-loop arrangement is essential for examining the protection system of the network after upgraded. The increments of SCC’s along a feeder may cause the existing protection devices installed at the original network and its customers’ distribution systems becoming inadequate. Hence, a simple, systematic and straightforward evaluation method is required, especially in the planning stage. To meet these requirements the short-circuit MVA method was adopted in this paper. Based on the adopted method, the variations of SCC’s along a primary feeder before and after the network upgraded were represented by simple formulas and illustrated by figures that make the variations more easily be recognized. The results|
confirm that the short-circuit MVA method is quite suitable for evaluating the variations of SCC’s along a feeder.
