Automatic Fault Location System of Distribution Network Based on Component GIS

针对配电网故障自动化定位系统定位准确度低的现状,将组件式GIS技术应用到配电网故障自动化定位系统设计中。硬件方面,重点设计了单片机、GPRS模块、ADC采样电路和信号零序调节电路,在系统软件部分,将遗传算法应用于精确故障定位,通过编码操作、构造转换函数、适应度函数构造三个部分来确定故障对象,在此基础上,采用组件式GIS设计数据库,将空间数据与属性数据关联,找出确定故障对象与属性文件的对应关系,实现配电网故障自动定位。通过仿真实验表明,此次研究的配电网故障自动化定位系统能够准确对配电网故障定位。

In view of the low positioning accuracy of the distribution network fault automatic location system,the component GIS technolo-gy is applied to the design of the distribution network fault automatic location system.In terms of hardware,it focuses on the de-sign of single-chip microcomputer,GPRS module,ADC sampling circuit and signal zero sequence adjustment circuit.In the sys-tem software part,genetic algorithm is applied to fault location,and the three parts are constructed through coding operation,con-struction conversion function,and fitness function.Determine the fault object,on this basis,use the component GIS to design the database,associate the spatial data with the attribute data,find out the corresponding relationship between the fault object and the attribute file,and realize the automatic location of the fault in the distribution network.The simulation experiment shows that the distribution network fault automatic location system studied this time can accurately locate the distribution network fault.
