摘要
家用负荷分类计量可引导家庭用户合理用电,同时加强需求侧管理。考虑家用负荷暂态特征的独特性,提出了以暂态波形为特征量在明可夫斯基距离测度基础上识别家用负荷启停来分别计量其电量的方法。首先在识别前建立家用负荷模板库以作为识别比较的标准。然后将采集的波形与模板库中的波形进行匹配度的计算,根据匹配度的大小得到负荷启停时间。最后,依据其启停时间计量各负荷用电量。该方法简单易懂,实测数据验证了该方法的可行性与准确性。
The measurement by classification of household load can guide home users to use electricity reasonably,and strengthen the demand side management.Considering the special transient characteristic of household load,a method was proposed to recognize the time it turns on or off,and then measure the electricity of each load based on Minkowski distance used transient waveform as signature.Firstly,it set up a template library to recognize the comparative standard,and then to calculate the matching degree between the waveform acquired and in template library to determine the time when the loads open or close.At last,it measured the electricity of each load.The method is simple,easy to use,and the measured data has proved the method has high accuracy and probability.
