摘　　要：针对交直交型电力机车的谐波问题,以CRH1型电力机车为研究对象,简要分析交直交型电力机车原理。采用基于瞬时无功功率的i_(p)-i_(q)检测法,建立MATLAB交直交型电力机车仿真试验模型,对其并网产生的谐波进行分析与探讨,提出采用APF对其谐波进行治理,为改善电气化铁路电能质量提供理论参考。Aiming at the harmonic problem of AC-DC-AC electric locomotive,taking CRH1 electric locomotive as the research object,the principle of AC-DC-AC electric locomotive is briefly analyzed.Based on instantaneous reactive power i_(p)-i_(q) detection method,the MATLAB AC-DC-AC electric locomotive simulation experiment model is established,and the harmonic generated by its grid-connection is analyzed and discussed.APF is proposed to control the harmonic,which provides theoretical reference for improving the electric power quality of electrified railway.
