摘　　要：为进一步提升配网运行稳定性、有效避免停电事故扩大,针对配网人工巡线方式费时费力、故障查找效率低下及故障指示器频繁误判拒动导致故障研判准确率较低等问题,对配网自动化及故障定位算法进行分析研究,提出一种基于分布式监测及无线通信技术的配网故障智能化定位监测系统设计方案。系统采用分布式故障检测终端实时检测配网线路的电压及电流值,并依托无线通信实时传输故障信号至远程监控中心及抢修人员终端,有效缩短故障查找时间、提高故障定位处置效率。In order to further improve the stability of distribution network operation and effectively prevent the expansion of power outages,a design scheme for an intelligent distribution network fault positioning and monitoring system based on distributed monitoring and wireless communication technology is proposed to address the problems of time-consuming and labor-intensive manual line inspection,low efficiency in fault finding,and frequent misjudgment and refusal of fault indicators leading to low accuracy in fault analysis and judgment.The system adopts distributed fault detection terminals to collect real-time voltage and current status of distribution lines,and relies on wireless communication to transmit fault signals in real-time to remote monitoring centers and repair personnel terminals,effectively shortening fault search time and improving fault location and disposal efficiency.
