摘　　要：为满足谐波监测与谐波源定位的需要,提出了一种电力谐波云监测系统方案。基于AM4377系统设计了电能质量检测装置,介绍了其硬件实现和基于瞬时无功理论的谐波检测算法。利用芯片内部的捕陷功能实现了精确测频与同步采样,提高了测量精度。利用无线网络将监测点的电能参数与谐波数据上传至云端分析系统,能够实现电网中多个监测点的高速同步谐波信号采集与分析。In order to meet the needs of harmonic monitoring and harmonic source location,a scheme of power harmonic cloud monitoring system is proposed.A power quality detection device is designed based on AM4377.The hardware implementation and harmonic detection algorithm based on instantaneous reactive power theory are introduced.Using the trap function in the chip,accurate frequency measurement and synchronous sampling are realized,and the measurement accuracy is improved.The wireless network is used to upload the power parameters and harmonic data of monitoring points to the cloud analysis system,which can realize the high-speed synchronous harmonic signal acquisition and analysis of multiple monitoring points in the power grid.
