摘　　要：随着中国电气化铁路的快速发展,列车及牵引网系统的非线性、强耦合特征愈加明显,随之带来的车一网电气振荡问题严重影响了电网和列车的安全稳定运行。本文分别概述了车一网系统低频振荡、谐波谐振和谐振不稳定等电气振荡现象及其危害,并总结了国内外学者对不同振荡现象在分析方法、失稳机理以及抑制策略方面的现状与探究,最后结合工程应用分别对今后的工作进行了展望。该总结研究可为车一网系统的稳定性分析、电气振荡治理和预防工作提供一个全面的参考。With the rapid development of China's electric railway,the nonlinear and strong coupling characteristics of the train and traction grid system have become increasingly distinctive,resulting that electrical oscillations have seriously affected the safe and stable operation of the power grid and trains.This paper firsdy outlines the electrical oscillation phenomena such as low-frequency oscillation,harmonic resonance and resonance instability of train-grid systems and their damages;then,the current status and investigations of scholars are summarized on different oscillation phenomena in terms of analysis methods,instability mechanisms and suppression strategies;Finally,some outlooks on future work are given with engineering applications respectively.The study can provide a comprehensive reference for the stability analysis,electrical oscillation management and prevention of train-grid systems.
