Abstract
Harmonics in power distribution systems have become a critical concern due to the increasing use of nonlinear loads, such as power electronics and variable speed drives. These harmonics cause distortion in voltage and current waveforms, leading to equipment malfunction, increased losses, and power quality issues. This manuscript explores harmonic sources, their effects on distribution systems, and presents methods for harmonic analysis based on classical techniques available until 2019. A detailed literature review covers modeling approaches, standards, and mitigation techniques. Statistical analysis highlights typical harmonic distortion levels in various systems. Methodology includes mathematical modeling, harmonic load characterization, and simulation using conventional tools. Results demonstrate the impact of harmonics on system performance and validate the effectiveness of mitigation strategies. The paper concludes with recommendations for improved harmonic management in power distribution networks.
