谐波检测及数据压缩在智能计量终端中的应用
Application of Harmonic Detection and Data Compression in Smart Metering Terminal
摘要
Abstract
This paper proposed a realizable method for harmonic detection in metering automation terminal for Guangdong power grid Corporation's requirements of application of harmonic detection technique in electric energy metering automation system.We investigated the EDIT-FFT (equal decimation in time fast Fourier transformation) algorithm to process the sampled signal to get the harmonic distortion rate,then combined with the characteristics of electric energy data which is fixation,smooth,short,the RAY-Period compression algorithm was firstly applied to intelligent measuring automation terminal.It saves the storage space and solves the communication problems of terminal and main station.This research lays a solid foundation for perfect function of the electric energy metering automation system of Guangdong power grid.关键词
