摘要
设计了一种能够测量电压偏差、频率偏差、谐波含有率、电压波动和闪变、三相电压不平衡度等电能质量指标的综合在线监测系统。系统由TVS1908型电压互感器和TAS1907-01型电流互感器以及USB总线的数据采集卡NI-6210构成简单硬件电路,以LabVIEW图形化软件编程代替传统硬件,实现了电能质量各项参数的测量和在线实时显示、数据共享和远程通信。与传统的电能质量分析仪相比,系统具有操作简单、监测参数多、所需硬件少、处理能力强、扩展灵活等优点。
A kind of online monitoring system,which can measure power quality performance including voltage deviation,frequency deviation,harmonic content,voltage fiuctuation and fiickering,unbalanced degree of three-phase voltage,was designed. The hardware circuits were composed of the potential transformer TVS1908,the current transformer TAS1907-01 and the data acquisition card（DAQ） NI-6210 with USB. Traditional hardware was replaced by LabVIEW graphical programming software. Each parameter of power quali-ty could be measured and displayed on real time,data shared and telecommunication realized. Compared with traditional power quality instrument,this system is in possession of easier operation,more parameters of monitoring,less hardware,stronger processing capa-city,more convenient extension etc advantages.
