基于谐波特征矩阵的负载识别

给出一种基于电流谐波特性矩阵的负载识别方法，并利用二进制数独立不重复的特性，给出了求多个数据随机组合计算值的算法。此方法首先采样计算各单一负载的谐波特性，利用随机组合计算算法得到各种负载组合后的谐波特性矩阵。之后实时地计算当前电网中的电流谐波值，并将此值与谐波特性矩阵中的数据进行比对，与吻合数据对应的负载即为当前工作在电网中的负载。此方法在试验中取得了很好的效果。

Load Characteristic Identification Based on Characteristic Matrix of Harmonics

This paper gives a load characteristic identification method based on harmonics of current.Since binary numbers are independent of one another, a algorithm of random combination calculating multiple data has been given in this paper.This method firstly samples and calculates the harmonics of current,and gets the matrix of harmonics which combine randomly, then samples and calculates the harmonics of current in real time,querying those values in the matrix of current''s harmonies,and the one which is consistent with the real time values is the load in electric network.
