摘要
电力系统谐波检测为谐波治理提供了方向,同时也是谐波监测系统的核心.本文首先阐述了电力系统谐波的诸多危害;其次对一些传统检测方法和近期新方法展开讨论和分析,比如瞬时无功功率法、快速傅里叶变换法、小波变换法、希尔伯特-黄变换法等;最后阐述了将来谐波检测领域的发展趋势.
Power system harmonic detection provides the direction for harmonic control and is also the core of the harmonic monitoring system. This paper first expounds the many hazards of power system harmonics, and then discusses and analyzes some traditional detection methods and recent new methods, such as: instantaneous reactive power method, fast Fourier transform method, wavelet transform method, Hilbert-Hang transformation method, etc., finally pointed out the future development trend and personal outlook in the field of harmonic detection.
