摘　　要：为满足电网谐波的快速检测与分析需要,研制了一种智能化的电能质量感知模块。智能感知模块使用Xilinx Zynq-7000 SoC系统平台采集检测点的数据并进行电能质量指标计算;同时利用4G/5G移动网络技术,将采集测点数据传到云端以实现对电网谐波的监测与定位。实例表明:利用SoC内的FPGA实现硬件同步采样,能准确地检测出所测信号基波与各次谐波的幅值与相位。In order to meet the needs of rapid detection and analysis of power grid harmonics,an intelligent power quality perception module was developed.The intelligent perception module used the Xilinx Zynq-7000 SoC system as the platform to collect the data of the measuring points and calculated the power quality index,and used 4G/5G mobile network technology to transmit the collected measuring point data to the cloud for realization of monitoring and positioning of grid harmonics.The example shows that the use of FPGA in the SoC to realize hardware synchronous sampling can accurately detect the amplitude and phase of the fundamental wave and each harmonic of the measured signal.
