说明：  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。
(Miniaturization, low cost and easy to live installation are the development direction of line phasor measurement unit (PMU) in distribution network. The article has been designed in this articleA new distributed PMU device used in the wide area measurement system of distribution network. Acquisition of a high-density induction module from the line The power is supplied to the device, and the circuit board (PCB) Roche coil is used to measure the line current, and the space capacitance pressure sensor is used. The current line voltage measurement, through distributed synchronous sampling to realize the acquisition of the voltage and current of the whole network, is the research of the new distribution network line PMU.)
