基于单片机的交流窜入直流监测仪的设计

Design on the Monitoring Equipment of AC Intrusion into DC Based on Single-chip Microcomputer

针对变电站直流母线有交流电源窜入的问题,提出了利用单片机作为核心控制芯片开发交流窜入直流的监测仪设计。所设计设备对直流母线进行在线监测,能够实时显示母线电压和窜入交流的有效值,从而提高了直流系统的可靠性,具有操作简单、测量准确、稳定性好的优点。

According to the problem of AC intrusion into DC system in substation,this paper puts forward the monitoring equipment design of AC intrusion into DC system,which using single-chip microcomputer as the core chip. The apparatus for online monitoring of DC bus can display the value of DC bus and the effective value of AC intrusion into DC system,so improves the reliability of DC system. The product has the advantages of easy operation,accurate measurement and good stability.
