    摘 要: 鐵磁諧振會產生過電壓現象,導致設備的絕緣破壞,影響系統的正常運行。利用電壓互感器的伏安特性曲線分段擬合出鐵心的鐵磁特性曲線,采用MATLAB-SIMULINK 軟件對110 kV 變電站的電磁式電壓互感器與斷路器斷口電容串聯產生的鐵磁諧振進行仿真分析;在此基礎上對消除此種鐵磁諧振事故的三種方法:使用電容式電壓互感器、拆除斷路器的斷口電容、采用伏安特性好的電磁式電壓互感器進行仿真分析,結果表明三種方法都能達到預期目的。
    關鍵詞: 鐵磁諧振;勵磁特性;電磁式電壓互感器;電容式電壓互感器;消諧措施

    Abstract: Ferromagnetic resonance will generate overvoltage phenomena to cause insulation damages of equipment and to impact on normal operation of the system. The volt-ampere characteristic piecewise curves were used to get the ferromagnetic curve of iron core. MATLAB-SIMULINK software was adopted to carry out simulation analysis for ferromagnetic resonance by connecting 110 kV substation electromagnetic voltage transformer with circuit breaker fracture capacitor in series. On the basis of this, three kinds of methods, including voltage transformer using capacitor, fracture capacitors demolishing circuit breaker and electromagnetic voltage transformer with good volt-ampere characteristics, were adopted to eliminate ferromagnetic resonance. The result shows that the three kinds of methods all can reach the expected goal.
                       Key words: ferromagnetic resonance; excitation characteristic; electromagnetic voltage transformer; capacitor voltage transformer; resonance elimination
