- The ferromagnetic resonance overvoltage of power system often occurs for a long time, which seriously endangers the safe operation of electrical equipment and power grid. The feature extraction and recognition of ferromagnetic resonance overvoltage is helpful for taking targeted measures to restrain overvoltage quickly, and it is of great significance to guarantee electric power system running in reliable and steady status. Based on the analysing the over-voltage and over-current waveform characteristics of different resonance types by EMTP simulation software, a method of ferromagnetic resonance overvoltage recognition is proposed which is named earth capacitance and excitation inductance ratio. The theoretical foundation of this method is visualized, and a lot of actual data show that this method is feasible and effective in ferromagnetic resonance overvoltage recognition.
