摘要
电气化铁路因其供电能力强、速度快、安全高效,在国内外得到快速发展,但川藏铁路目前存在三相电力供电能力弱、电能质量难以达到国家标准要求等问题。针对高原铁路存在的问题,提出了一种基于组合式变换器贯通供电方案。首先,分析了系统结构和原理;其次,采用Matlab仿真软件进行3个变电所的建模仿真。仿真结果表明,基于组合式变换器的贯通供电系统主要电气性能均能达到国家标准要求,仿真结果证实所提方法的有效性。
Electrified railways have developed rapidly at home and abroad due to their strong power supply capacity,fast speed,safety and efficiency,but Sichuan-Tibet railways currently have problems such as weak three-phase power supply capacity and its power quality is difficult to achieve the national standard requirements.Aiming at the existing problems of plateau railways,a through power supply scheme based on combined converters is proposed.Firstly,the system structure and principle are analyzed,and then the Matlab simulation software is used to model and simulate three substations.The simulation results show that the main electrical performance of the through power supply system based on combined converters can meet the national standard requirements,and the results confirm the effectiveness of the proposed method.
