Distribution network fault diagnosis algorithm based on GIS platform

为了快速确定配电网故障点的位置,并给出故障处理方案,通过分析地理信息系统(GIS)平台配电网拓扑结构,在基于空间搜索技术的故障诊断基础上,引入了关键设备的简化结构及其数学模型。运用矩阵描述了开关状态及拓扑关系,利用基于矩阵运算的电网故障诊断算法,设计了基于GIS平台的故障诊断模块。工程应用中结合现有GSM/GPRS通信方式,实现了开关状态的快速检测。通过GIS仿真平台,可以自动生成故障处理操作票,从而为故障的快速定位及处理提供了方便。

Based on the fault diagnosis with space search technique,the simplified structure of key equipments and their mathematical models are introduced into the distribution network topology on GIS platform to quickly locate the fault and provide countermeasures.The breaker states and their topology are described by matrix and the distribution network fault diagnosis algorithm based on matrix calculation is applied to design the distribution network fault diagnosis module on GIS platform.Combined with the existing GSM/GPRS communication mode,the breaker states are quickly detected and the fault removal operation order is automatically generated on GIS simulation platform.
