摘要
文章在模拟仿真了含有高斯白噪声的电能质量扰动信号的基础上,给出利用正交小波包算法对电能质量扰动信号进行检测和定位的方法。研究结果表明,该方法有更好的检测性能,能更精确检测瞬态扰动发生的时刻和持续时间。
On the basis of simulating the power quality disturbance signal with Gaussian white noise, this paper presents a method to detect and locate the power quality disturbance signal by using orthogonal wavelet packet algorithm. The results show that the method has better detection performance and can detect the time and duration of transient disturbance more accurately.
