Approach to Short Circuit Current Calculation in Distribution System Based on GIS Platform

A newly visual short circuit current calculation approach in terms of geographical information system (GIS) is proposed in distribution system. Thus the combination of GIS and short current calculation method is achieved whilst users don't need to spend a lot of time on inputting data or modeling. Furthermore, the superposition theorem is then adopted in the approach, which overcomes the difficulties when applying the symmetrical components to the short circuit calculation. Calculation result keeps in line with the constitution of distribution system and the device has high efficiency.
