Summary:The invention relates to a high-power electric arc furnace low-frequency inter-harmonic emission characteristic analysis method and system, and the method comprises the steps: respectively processing signals describing voltage fluctuation and low-frequency non-stationary inter-harmonics through a trigonometric function decomposition method, and determining a mutual influence mechanism of the low-frequency non-stationary inter-harmonics and the voltage fluctuation; the signals describing the voltage fluctuation and the low-frequency non-stationary inter-harmonics are processed through a mathematical analysis method, and the quantitative conversion relation between the low-frequency non-stationary inter-harmonics and the voltage fluctuation is determined; according to the law of conservation of energy and the chaos dynamic model, an alternating-current electric arc furnace simulation model for describing low-frequency non-stationary inter-harmonic emission characteristics is established; acquiring voltage and c
