中文摘要:

为了实现对多台逆变器电能质量的实时监测,设计了基于LabVIEW的分布式逆变器电能质量监测系统。该系统应用了虚拟仪器技术和以太网通讯技术,以现场子系统驱动数据采集卡,实时地采集逆变器电能信号,并通过UDP通讯协议将采集到的数据发送到指定站点的远程监测子系统中。站点系统利用接受到的数据进行电能信号频率、功率、三相不平衡度和各次谐波分量等电能质量指标的分析,并建立数据库对采集到的电能信号数据和指标计算结果进行存储,分类和共享,为进一步的电能质量分析奠定了基础。

英文摘要:

A distributed inverter power quality monitoring system based on LabVIEW is designed to monitor the power quality of multiple inverters, which applies the virtual instrument technology and Ethernet communication. And combining with the data acquisition card, this system is able to acquire inverter power signals in real-time and send the these signals to remote monitoring system by the Ethernet communication protocol UDP. Based on the data received, the remote system analyzes the power quality indexes such as frequency, power, three-phase unbalance factor and harmonic content. The received data and calculation results will be stored, classified and shared through database, which establishes a solid foundation for the further analysis of power quality.
