摘　　要：为了准确快速地分析大规模10 kV配电网设备短路电流水平,提出了一种基于地理信息系统(geographic information system,GIS)拓扑数据的配电网短路电流算法。该算法基于配电网GIS的设备拓扑数据及常规电网数据,将配电网10 kV设备简化成各个节点模型与支路模型,运用Excel的计算模块实现大规模配电网设备节点的短路电流水平计算。以东莞电网为例进行断路器短路电流仿真计算,结果表明该算法能够实现配电网大规模数据处理,快速计算设备短路电流。To accurately and quickly analyze short circuit current of large-scale,10 kV distribution network equipment,this paper proposes a kind of short circuit current algorithm based on topological data of the geographic information system(GIS).This algorithm is based on topological data of the GID equipment and conventional power grid data and simplifies 10 kV equipment into each node model and branch model.Meanwhile,it uses Excel calculation module to realize calculation on short circuit current of equipment node of the distribution network.Dongguan power grid is taken as an example for simulating calculation of breaker short circuit current and the result indicates this algorithm can realize large-scale data processing of the distribution network and quickly calculate equipment short circuit current.
