Abstract
With the widespread application of modern power electronic devices, harmonic pollution in power systems has become increasingly severe, not only affecting power quality but also posing a threat to the stable operation of power systems. To address this issue, this study investigates harmonic analysis and mitigation methods in power systems, aiming to propose effective harmonic suppression strategies by integrating theoretical analysis with practical applications. Based on mathematical tools such as Fourier transform, precise analysis of harmonic components in power systems is conducted, and a harmonic source model is established. The validity of the model is verified through field measurement data. On this basis, a comprehensive management solution combining active power filters (APFs) and passive power filters (PPFs) is proposed, which can dynamically adjust filtering parameters according to the actual conditions of the power grid, achieving effective suppression of harmonics at different frequencies. Experimental results demonstrate that the proposed comprehensive management solution significantly reduces harmonic distortion rates and improves power factor, enhancing overall performance by approximately 30% compared to traditional single-filter approaches. Additionally, this study innovatively incorporates intelligent optimization algorithms for optimizing filter parameters, further improving the adaptability and robustness of the system. This provides new insights and technical means for harmonic mitigation in power systems, playing a crucial role in enhancing power quality and operational stability.
