摘　　要：朔黄铁路线长点多,用电负荷性质差异较大且分布不均,线路断线、单相接地故障或电源分合闸时,容易引起系统震荡,导致铁磁谐振。结合微机消谐装置在朔黄铁路设计及运营中的实际应用情况对其工作的基本原理及功能作了阐述,对现场发生的实际问题对其应用效果进行了分析,并根据采取改进措施后的消谐方案提出了问题和建议。with heavily interspersed stations on far extent of Shuo-Huang Railway, with uneven, heterogeneous electric load permanent on, system oscillation may happen from break of circuit, single-phrase earthing fault or operation of switch-on/off, that may result in ferromagnetic resonance. Now we, taking Shuo-Huang Railway for example, provide you with the basic principle and function of computer-operated harmonic damper, the analysis on practical matter arisen in the field and the effect of this application. Questions and suggestions are also presented herein on the proposed improved harmonic damper.
