中文摘要:

电网谐波和间谐波的实时精确检测的重要性日益突显。本文按平稳信号和非平稳信号的划分,论述用于谐波和间谐波检测的傅里叶变换法和小波变换法、S变换、人工神经网络法、谱估计法以及希尔伯特-黄变换法,并指出各种检测方法的优缺点及其应用。最后对各种检测算法进行了总结和展望。

英文摘要:

Real-time accurate detection of the harmonics and inter-harmonics in power grid becomes increasingly prominent. In this paper, the methods for harmonic analysis are divided into two parts according to their application to detect stationary or non-stationary signals. Various methods and their characteristics, such as Fourier transform, wavelet transform, S-transform, artificial neural network, spectrum estimation and Hilbert-Huang transform are discussed in details. Finally, the paper provides a summary and outlook for all the detection methods.
