摘　　要：电气化铁路运行过程中,系统不仅存在低次谐波,还存在大量的高次谐波,这是由于电气化铁路主要运营着的交直交型机车,在行驶过程中和供电系统电气匹配不当,会使机车产生谐波并注入电网。为了能够有效抑制高速铁路的谐波谐振,基于电气化铁路的谐波特性,利用单调谐滤波器以及高通滤波器设计出了一种新型组合而成的无源滤波器的抑制高频谐波谐振策略,并证明了此设计的有效性。During the operation of the railway electrification system,the system not only has low harmonics,but also has a large number of high harmonics,which is due to the fact that the railway electrification system mainly operates an AC-DC locomotive,in order to suppress the harmonic resonance of high-speed railway effectively,based on the harmonic characteristic of the railway electrification system,the harmonic resonance of the high-speed railway can be generated by the locomotive if the locomotive is not matched with the electric power supply system,a strategy for suppressing high frequency harmonic resonance using a combined passive filter and a single tuned filter is proposed,and the effectiveness of the design is demonstrated.
