一种新的电能质量扰动分类识别算法

通过分析电能质量扰动信号的时域特征,提出一种电能质量扰动分类方法.所提取的扰动分类特征量具有明确的物理意义,有利于对各种电能质量扰动进行估值.某一特征量或某几个特征量能唯一确定一种扰动,使扰动判断不再具有或然性.任一扰动的特征量不因其他扰动的存在而改变.因此,可以准确辨别出混合扰动.MATLAB仿真结果表明,该方法能有...

A New Disturbance Classification Recognizing Algorithm of Electric Energy Quality

A novel classification of power quality disturbance has been proposed by analysising of power quality disturbances in the time-domain characteristics of signals.the classification has a more clear physical meaning,so it is useful to evaluation of power quality disturbances.a feature or a number of features determine a disturbance uniquely in order to eleminate error of evaluation.One of the features of disturbances is undepend on any others,so it can accurately identify mixed disturbance.MATLAB simulation results show that this method is effective in classification of single and mixed power quality disturbances,and less time-consuming of calculation.
