摘　　要：10 kV系统铁磁谐振严重影响配网系统安全稳定运行,在考虑配网谐振抑制措施时研究者往往针对单独某一种措施进行分析。文中以曾经发生过铁磁谐振故障的某110 kV变电站10 kV系统为分析对象,在电磁暂态分析软件ATP-EMTP中建立仿真模型,考虑了消谐器、改变励磁特性、阻尼电阻3种抑制措施,分别对单一措施抑制效果和不同措施组合使用抑制效果进行了分析。分析表明,针对文中研究对象,不同抑制措施组合使用效果优于单一措施。不同抑制措施综合使用,为配网铁磁谐振的治理提供了新的思路。Ferromagnetic resonance seriously influences the security and stability of 10 kV power systems. When studying the suppression method of distribution network ferromagnetic resonance, the researchers usually consider the individual method, and comprehensive suppression method has not been widely mentioned. This paper selected the 10 kV system of a 110 kV substation which ferromagnetic resonance has happened as analysis object, simulation models of distribution network ferromagnetic resonance are built based on electromagnetic transient analysis software ATP-EMTP. Three kinds of suppression measures are considered, which are the harmonic eliminator, change the excitation characteristics and damping resistance, single measure and different measures combination are analyzed is obtained by use suppression methods in combination. A new respectively. By idea is provided the suppression effects of comparison excellent result in this paper for governing ferromagnetic resonance.
