摘　　要：铁磁谐振是配电网运行中的一种常见现象,多发生在中性点不直接接地的配电网中。谐振导致的过电压和过电流往往会使电压互感器(TV)过热烧毁,影响线路的正常运行。文章针对铁磁谐振的发生机理及其分类进行了概述,并对当前研究铁磁谐振的各种方法和消谐措施做了总结。Ferro-resonance is a common phenomenon in the operation of distribution network, which occurred in the neutral un-directly grounded distribution network. Resonant leads to the over-voltage and over-current, often causes PT overheated and destroyed, and affects the normal operation of line. This paper described the mechanism and classification of ferro-resonance, and summarized the methods and measures for current research of ferro-resonance.
