摘　　要：为改善中车青岛四方10 kV/25 kV电气化铁路动调试验线路中存在的负序、谐波及负荷冲击等电能质量问题,顺应以复兴号及和谐号为代表的重载化、高速化机车负荷的潮流特性,提出了一种基于制动能量消纳模块和三相-单相变换的新型谐波消除电源(BECM&TSC-HES)。该电源方案由18套供电单元采用级联方式构成,每套供电单元中整流侧采用基于移相整流变压器的不可控整流电路,逆变侧采用基于IGBT模块的H桥级联逆变电路,同时直流侧配有基于刹车电阻的制动能量消纳电路。试验结果充分证实了系统的有效性及正确性。In order to solve the power quality problems existed in the CRRC Qingdao Sifang’s 10 kV/25 kV electrified railway dynamic-tuned experiment line,such as negative sequence,harmonics and load impact,and to conform to the trend of the characteristics of high-capacity and high-speed locomotive,represented by China Fuxing and Harmony,a novel breaking-energy consumption module and three-phase to single-phase converter based harmonic elimination source(BECM&TSC-HES)is proposed.The method is composed of 18 sets of power supply units in a cascade connecting mode.Meanwhile,the uncontrolled rectifier circuit based on rectifier phase-shifting transformers is adopted in the rectifier side of the system,and the H-bridge cascaded inverter circuit based on IGBT module is adopted in the inverter side,whilst the breaking-energy consumption module with brake-resistance is used.The experimental results verify the effectiveness and correctness of the system.
