一种基于 FPGA 的电能计量算法研究
Research on an electric energy metering algorithm based on FPGA
摘要
Abstract
With attention to power quality, the application of power quality analyzer becomes more widespread.The e-lectric energy metering system designed in this paper uses the programmable logic device FPGA as digital processing core, integrates grid frequency tracking, simultaneous sampling, measurement of basic electrical parameters, FFT harmonic analysis and other functions.It uses digital filter to achieve Hilbert transform and an accurate measurement of reactive power under the non-sinusoidal voltage waveform.The experiments have showed that power quality analyzer based on FPGA has the advantages of strong real-time performance, high accuracy, reliability and etc.关键词
