ABSTRACT
With the rapid development of modern industry and the wide application of power electronics technology, the power quality problem is increasingly prominent, which has a serious impact on the safe and stable operation of the power grid and the normal work of the power equipment. Therefore, this study focuses on the application of power electronic devices in power quality management, aiming to improve the effect of power quality management through advanced control strategy and hardware design. Using theoretical analysis, simulation modeling and experimental verification, the key technologies of dynamic reactive power compensation, harmonic suppression and voltage fluctuation control based on new power electronic devices are deeply discussed. The results show that the proposed static reactive power generator (SVG) scheme based on IGBT module can significantly improve the dynamic response speed and effectively reduce the system loss; and the active power filter (APF) combined with adaptive filtering algorithm shows excellent performance in harmonic governance, especially with higher compensation accuracy under nonlinear load conditions. In addition, a comprehensive optimization strategy is proposed to realize the collaborative governance of various power quality problems.
