摘要
针对反窃电过程中遇到的准确率低、及时性差以及稽查取证困难的问题,设计了一种基于印刷电路板(PCB)罗氏线圈的反窃电在线监测系统,其中高低压两侧间数据的传递通过ZigBee技术实现,检测数据则是由GPRS上传至远端服务器。设计了一种PCB罗氏线圈电流传感器,并对其结构及电磁参数进行仿真分析,最终制作了三种不同规格的PCB罗氏线圈电流传感器,灵敏度分别为3.23,3.52,2.0 mV/A。设计了一种基于距离的离群点反窃电算法,并对算法的可行性进行了仿真分析。结果表明:设计的基于PCB罗氏线圈电流传感器和离群点算法的反窃电在线监测系统有效可行。
Aiming at the problems of low accuracy,poor timeliness and difficulty in auditing and evidence collection in the process of anti-stealing,an anti-stealing online monitoring system based on printed circuit board(PCB)Rogowski coil is designed,ZigBee technology is used to realize data transmission between high and low voltage sides,the general packet radio service(GPRS)technology is used to upload the detection data to the remote server.A PCB Rogowski coil current sensor is designed,and its structure and electromagnetic parameters are simulated and analyzed.Finally,three PCB Rogowski coil current sensors of different specifications were produced,with sensitivity of 3.23,3.52 and 2.0 mV/A,respectively.A distance-based outlier anti-stealing algorithm is designed and the feasibility of the algorithm is simulated and analyzed.The results show that the designed anti-stealing online monitoring system based on PCB Roche coil current sensor and the outlier algorithm are indeed feasible.
