摘 要: | 为了避免交直交型电力机车(含动车组)与牵引供电系统之间形成谐波谐振,影响电气化铁路运行安全,有必要在牵引供电系统设计阶段开展谐波谐振特性分析。基于四象限变流器拓扑结构与控制策略,构建电力机车谐波源特性模型,针对某新建电气化铁路牵引供电系统设计方案,构建牵引供电系统数学模型,利用MATLAB/Simulink仿真平台,研究系统谐波谐振特性与变化规律,给出便于工程应用的滤波器设计方案,并验证该方案的可行性。

Abstract: | In order to avoid harmonic resonance,which is likely to occur between AC-DC-AC locomotive( including EMU) and traction power supply system and then pose a threat to the operation safety of electrified railway,it is necessary to carry out harmonic resonance characteristic analysis in the stage of traction power supply system design. In this study,based on four quadrant converter topology theory and control strategy,the harmonic wave source characteristic model of electric locomotive was established.Moreover,focusing on the scheme of traction power supply system of a certain newly-built electrified railway,a mathematical model of traction power supply system was established. In addition,by using simulation platform of MATLAB /Simulink,the harmonic resonance characteristics and change rule were researched. Finally in this paper,a wave filter design scheme suitable for being used in actual projects was put forward,and also its feasibility was verified. |
