摘　　要：小型化、低成本、易带电安装是配电网线路相量测量单元(PMU)的发展方向。文中设计了一种应用于配电网广域测量系统的新型分布式PMU装置。通过高密度感应取电模块从线路中获取能量为装置供电,采用印刷电路板(PCB)式罗氏线圈测量线路电流,利用空间电容分压传感器实现线路电压测量,通过分布式同步采样实现全网的电压、电流采集,为新型配电网线路PMU的研制提供了一种新的解决方案。目前,配电网线路PMU测试样机已实地测试并传回监测数据,装置各模块均能稳定正常工作,测量结果能正确反映线路电压电流。Miniaturization,low cost and easy installation with power on are the development directions of phasor measurement unit（PMU）for distribution network lines.A novel distributed PMU device designed for the wide-area monitoring system of distribution network obtains energy from the line through the high-density inductive power taking module.The device measures current and voltage waveforms by printed circuit board（PCB）Rogowski coils and spatial capacitive voltage divider,respectively,and achieves voltage and current collection in the whole network by distributed synchronous sampling.The device proposed provides a new solution for the development of novel PMU in the distribution network lines.At present,prototypes of PMU have been tested online and the monitored data have been sent back.All modules are found to work normally and stably and measurement results to accurately reflect the line current and voltage.
