交直交电力机车谐振原因分析与对策

摘要

Through the field test and analysis which aims at the voltage fluctuation phenomenon in railway passen- ger station, the author suggests it is mainly due to the imperfect putse width adjustment strategy of the four quad- rant pulse converters in AC/DC/AC electric locomotive or EMUs, the corresponding countermeasures are also given.%针对客运站接触网电压波动现象，通过现场测试分析，认为其主要原因是交直交机车或动车四象限脉冲变流器脉冲宽度调整策略不完善，并对此提出相应解决对策。
