Abstract
With the rapid development of rail transit, power electronics technology has been increasingly applied in traction power supply systems. To enhance the operational efficiency and reliability of rail transit systems, this study delves into the application and optimization strategies of power electronics technology in rail transit traction power supply. Based on an analysis of the existing traction power supply system architecture, this paper focuses on the working principles of key power electronic devices such as DC choppers and inverters, and their roles in the energy conversion process. By establishing mathematical models and conducting simulation analyses, a multi-ob jective optimization algorithm-based energy management strategy is proposed, which effectively reduces energy consumption and improves power quality. The research findings indicate that the proposed optimization scheme can increase system efficiency by more than 15% and reduce harmonic distortion to within 3%. Furthermore, addressing issues such as low power factor in traditional traction power supply systems, active filters and reactive power compensation devices have been introduced, achieving dynamic regulation and real-time monitoring functions. This study not only provides theoretical basis and technical support for the upgrade and transformation of rail transit traction power supply systems but also lays a solid foundation for future intelligent railway construction, demonstrating significant academic value and practical application prospects.
