Simulation and performance comparison of typical electric energy metering algorithms
摘要
Abstract
The principle and features of 5 kinds of typical and mature electric energy metering algorithms are intro-duced simply .Then ,the 5 algorithms are used to meter total electric energy , fundamental energy and harmonic energy under non-synchronous and synchronous conditions .So the relative errors and calculating times can be got .In gener-al, the relative errors are smaller when using Nuttall window double-spectrum-line interpolation based FFT algorithm , Rife-Vincent window double-spectrum-line interpolation based FFT algorithm and wavelet packet decomposition and reconstruction algorithm to compute total electric energy , while the relative errors are bigger when using wavelet packet decompasition and reconstruction algorithm , Prony algorithm and quasi-synchronous sampling based FFT algorithm to compute harmonic energy .And Nuttall window double-spectrum-line interpolation based FFT algorithm and Rife-Vin-cent window double-spectrum-line interpolation based FFT algorithm has betterreal-time performance than the other three kinds of algorithms .These conclusions can provide reference for practical applications .关键词
