Harmonic and interharmonic detection based on adaptive wavelet and improved EWT

Harmonic and interharmonic detection based on adaptive wavelet and improved EWT

To address the issues of noise sensitivity and over-decomposition when decomposing harmonic signals using empirical wavelet transform （EWT）， a method based on adaptive wavelet denoising and improved EWT is proposed for detecting harmonics and interharmonics. Firstly， to enhance the effectiveness of...
