复杂动态电能信号幅度域游程波形样本库的构建
Construction of run-length waveform sample library in amplitude domain of complex dynamic power signals
摘要
Abstract
Aiming at the impact of rapid change of complex dynamic power signal on the error of electricity meter,currently published papers only extract a few waveform samples for analysis,which cannot reflect waveform modes of various current variations,and do not further explore characteristics of power signal and its characterization.Therefore,The fundamental amplitude waveforms are extracted for 3 types of typical complex dynamic power sig-nals.Then,characteristic parameters of run-length and their characterization modes are proposed.On basis of ana-lyzing the typical features of amplitude domain,28 typical run-length waveforms can be extracted by further analy-zing multi-run-length characteristics of current amplitude,and then,the sample library of current characteristic waveforms can be established.According to the characteristic of run length,suggestion test points are given for sup-plementing international and domestic electricity meter standard.关键词
