摘要
电能质量信号中除了分析电能质量信号有用的信号外,还包含大量的噪声信号。介绍对现有电能质量信号去噪方法进行的分类;对近年来兴起的具有很好发展潜力的几种电能质量信号去噪方法进行描述;对其优缺点进行了总结;对今后电能质量信号去噪的研究方向进行了展望。
Except useful components for analyzing power quality, the power quality signals also contains a lot of noise. Several emerging effective de-noising methods for power quality signals during recent years were analyzed, including their merits and demerits. Further research on power quality signal de-noising was proposed.
