Harmonics Signal Feature Extraction Techniques: A Review

Harmonic estimation is essential for mitigating or suppressing harmonic distortions in power systems. The most important idea that spectrum analysis, waveform estimation, source classification, location, the determination of contributions, data clustering, and filter-based elimination capacity are also considered. feature extraction method a fundamental component optimization improves effectiveness Mitigation method. In this study, techniques to extract frequencies harmonics frequency domain, time spatial domain include 67 literature reviews an overall assessment. combinations signal processing with artificial intelligence (AI) reviewed evaluated study. benefit methods analysis extracts powerful basic information feedback signals from sensors redundancy, ensuring highest efficiency next sampling process algorithms. This study provides overview recent years, presentation their advantages limitations.
