摘要
Abstract
Urban subway transportation is one of the most important public transportation methods in our country,and analy-zing the power quality and energy efficiency of its traction power supply system are of importance for assessing the power quali-ty of urban power grids.This paper primarily focuses on the analysis of power quality and energy efficiency in DC traction pow-er supply system of a certain urban subway,which is in operation for many years,and seeks solutions for improvement.Through active current filtering and reactive power compensation,ensure that the traction substation operates under condition of unity power factor.The paper tests the performance of the the proposed filtering and regeneration system using the Simulink model,confirming the effectiveness of the proposed improvement solution.关键词
