摘要
Abstract
There are a large number of inductance and capacitance components in the power grid system.When the system is subject to electromagnetic disturbance,the equivalent capacitance of the system and the excitation inductance of the potential transformer(PT)are prone to parameter matching,which may further cause ferromagnetic resonance overvoltage.This overvoltage may have a serious impact on the power system,destroy the insulation performance of electrical equipment,and even cause equipment breakdown,seriously endangering the safe and stable operation of the power system.This paper analyzes the main causes and hazards of ferromagnetic resonance,and emphasizes the important value of ferromagnetic resonance research.This paper deeply analyzes the generation mechanism of ferromagnetic resonance,details the principles of fundamental frequency,fractional frequency,and high frequency ferromagnetic resonance phenomena,analyzes the resonance conditions,and proposes a method for accurately judging the type of ferromagnetic resonance.This paper reviews the current research progress of ferromagnetic resonance detection and summarizes several major detection methods and emerging technologies.This paper finally evaluates the current status of research on ferromagnetic resonance and looks forward to future research directions.关键词
