小波帧变换方法在电能质量扰动中的仿真分析

Modulation Analysis of Wavelet Frame Transform Method in Power Quality Disturbance

针对电能质量扰动问题,提出了小波框架和小波帧算法.将小波帧算法和传统的小波分析方法在算法框架上进行了比较,并进行了大量的实验.实验结果表明,基于小波帧算法的实时性有所减弱,但在扰动定位的准确性方面有很大提升.

In view of the electric power disturbances, wavelet frames and wavelet frames algorithm are proposed, and wavelet frames and the traditional wavelet analysis method are compared, and a lot of experiments are conducted. The experiment results show that the algorithm based on wavelet frames has lost some real-time features, but in the meantime, the disturbance positioning of the accuracy has greatly improved.
