摘要

在电力系统中引起电网过电压的原因很多

其中电压互感器铁磁谐振过电压出现频繁

危害性较大。过电压一旦发生

往往会造成电气设备的损坏

甚至出现严重的停电事故。基于铁磁谐振现象的复杂性

笔者从一个550 kV气体绝缘金属封闭开关设备（GIS）工程着手

选取可能发生铁磁谐振的12种典型工况

采用铁磁谐振仿真软件进行计算

依据结果分析发生铁磁谐振的规律性

提出预防性应对措施

使危害降到最低。

Abstract

Over-voltage caused by many reasons in the power system

where the voltage transformer ferromagnetic resonant overvoltage occur frequently

has great harmfulness. Over-voltage occurs often caused by the damage to the electrical equipment

even a serious power failure accident. Based on the complexity of the ferromagnetic resonance phenomenon

this paper started from a 550 kV gas insulated metal-closed switchgear（GIS） project

selected 12 possible kinds of typical ferromagnetic resonance conditions

and calculated from the simulation software of ferromagnetic resonance. According to the result of the regularity occurrence of ferromagnetic resonance

this paper proposed preventive countermeasures that minimize harm.
