摘要
      A real-time power quality measurement method based on three-phase electric energy metering chip V9203 DMA mode is proposed, and the circuit is designed. It realizes the Fourier algorithm based on accurate frequency measurement algorithm and AC sampling algorithm, and accuracy of measurement results within a large frequency fluctuation range is ensured. The test results show that compared with using other metering chips,  this method has the advantages of fast dynamic response, high accuracy and simple circuit design. Compared with traditional high performance ADC circuit methods, this method can greatly reduce the cost of product hardware.
