摘要
针对复杂动态电能信号的快速变化对电能表误差造成的影响,目前公开发表的论文仅提取了少数波形样本进行分析,无法反映多种电流变化的波形模态,也未更深入挖掘电能信号的特征及其表征问题。因此,提取了3类典型复杂动态电能信号的基波幅度波形;提出了游程特征参量及其表征方式;在分析幅度域典型特征的基础上,对电流幅度的多游程特征展开分析,提取出28个典型游程波形,建立了电流特征波形样本库;根据典型游程波形的游程长度,提出了补充国际和国内标准试验点的建议。
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.
