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 ,也曾经发生过这种过电压。针对中性点接地方式不同的两种情况 ,对近年来铁磁谐振的研究及其进展情况进行分析 ,分别介绍了其产生的机理、特征 ,评价了国内常见的几项消除谐振的措施或装置 。
Ferroresonance is an internal over voltage, which always occurs in neutral isolated distribution net, and sometimes also occurs in high voltages network. Aiming at the two different modes of the neutral points, the research developments on ferroresonance are analyzed, including their fundamental principles, characteristics, several ways to suppress ferroresonance and further research trends.
