摘要
该文基于虚拟仪器介绍了一种便捷的电力系统谐波失真测量方法。利用电压互感器和NI myDAQ采集卡采集实际电网信号,在LabVIEW2017中配置DAQ助手、频谱测量模块和失真测量模块。该设计能够快速并且较准确地测量出实际电网的信噪比和总谐波失真。
This paper introduces a convenient method of harmonic measurement and analysis in power system based on virtual instrument.The voltage transformer and NI myDAQ acquisition card are used to collect actual power grid signals.DAQ assistant,spectrum measurement module and distortion measurement module are configured in LabVIEW2017.The design can measure the signal to noise ratio and total harmonic distortion of the actual power grid quickly and accurately.
