摘　　要：介绍了一种基于地理信息系统(GIS)的配电网可视化短路电流计算方法,实现了GIS与短 路电流算法的有效结合,避免了用户手动建模的繁琐工作。采用基于叠加原理的短路电流计算方 法,克服了传统的对称分量法应用于配电网短路电流计算时所遇到的困难。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.
