摘要
运用Melnikov方法首次对电力系统的铁磁谐振过电压现象进行了浑沌振荡研究,证实了谐振过电压就是一种浑沌振荡的表现形式,得出了浑沌发生区域及浑沌阈值,为研究这种现象提供了新的理论方法和计算公式,并为认识它的性质提供了科学依据.
In this paper,the Melnikov method is used for the first time to analyse the chaotic oscillation of ferromagnetic resonance overvoltage in power systems. It is proved that resonance overvoltage is just a form of experession of chaotic oscillations.The chaos regions and threshold are obtained. A new theoretical method and calculating formula are provided for studying this phenomenon. Thus, the scientific basis is provided for understanding its characteristics.
