A hybrid simulation model of AC electric arc furnace

摘要：

A hybrid simulation model of AC electric arc furnace is proposed, which is useful for both power quality analysis and electric arc control research. The lack of knowledge of quantifying expression due to the complex nature of the AC electric arc system was overcome by parameter estimation. Combined the advantage of two existent typical electric arc model, a hybrid simulation model of AC electric arc furnace was deduced. A novel formula between the arc voltage and arc length and arc current was put forward to. In order to get the concerned parameters of the AC electric arc model, simulation analysis and numerical value calculation were used on the basis of theoretical deduction. At last, the proposed model was simulated in Matlab. Comparing the simulated results with the measurement data, it is shown that the model can accurately represent the AC electric arc furnace process. The developed model is valid and easy to use.
