铁磁谐振过电压摘要:铁磁谐振过电压是一种常见的内部过电压,多发生在中性点不直接接地的配电网中,但在中性点直接接地的高压电网中,这种事故也常有发生。分析了电力系统铁磁谐振的产生机理,介绍了一些典型的铁磁谐振过电压,以及几种消除铁磁谐振的措施及原理,最后对铁磁谐振的当前研究现状进行了评价,提出今后进一步的研究方向。关键词:电力系统;铁磁谐振;过电压;消谐措施Abstract:Ferroresonance is an internal overvoltage,which always occurs in neutral isolated distribution network, and sometimes also occurs in high voltages network. The research developments on ferroresonance are analyzed,including their fundamental principles, characteristics and some typical examp
