摘要
车网低频振荡机理是目前电气化铁路高速发展亟待解决的关键问题。基于阻抗比判据,推导出分析车网系统低频振荡的判据公式,在此基础上,全面推导、分析了车网各种参数对车网低频振荡的影响,并探索出重要的结论和规律。最后对实际的车网低频振荡事故进行了复现和分析,并验证了本文车网低频振荡机理分析的正确性,为全面掌握车网低频振荡机理以及制定相应的抑制措施提供了重要的参考和理论依据。
Low frequency resonance mechanism for locomotives and grid of the electrified railway needed to be solved urgently.Based on the impedance ratio on the stability of criterion,influence of all kinds of locomotives and grid parameters for the low frequency resonance were analyzed,and the important rules and conclusions were found.Finally,reproduced and analyzed the actual low frequency resonance accident,all the work was verified.An important reference and theoretical basis were provided for fully grasp the low frequency resonance mechanism and developing appropriate suppression measures.
