摘要
分析机车的谐波特性与谐波谐振产生机理,对比实测数据对应的谐波特性与机车谐波特性,提出一种适用于低次奇次谐波与高次谐波带并存情形的混合无源滤波器,并对该滤波器的结构与阻抗频率特性以及典型系统情况下对牵引网谐振特性的影响进行介绍。设计一套混合无源滤波器装置,并通过建立牵引网仿真模型对滤波前后牵引侧母线谐波含量进行测试和分析,验证滤波装置的可行性和有效性。
The harmonic characteristics and harmonic resonance mechanism of locomotive are analyzed.By comparing the harmonic characteristics of the measured data with that of the locomotive,a hybrid passive filter is proposed,which is suitable for the case of low order odd harmonic and high order harmonic bands coexisting.The structure and impedance frequency characteristics of the filter as well as the influence of the typical system on the resonance characteristics of the traction network are introduced.A hybrid passive filter is designed.Through the establishment of traction network simulation model,the harmonic content of traction side bus before and after filtering is tested and analyzed to verify the feasibility and effectiveness of the filtering device.
