Abstract：As a typical impact and pollution load in power systems, electric arc furnace (EAF) seriously affects power quality. The characteristics of nonlinearity, time-variation, randomness increase the difficulty in comprehensive improvement and harness of power quality. Due to the diverse usage of industrial electric arc furnaces, it is difficult to build accurate versatility model that can reflect the electrical characteristics of different types of EAF currently. Firstly, the process of energy dissipation is analyzed, which proves the consistency of EAF energy exchange process under different industrial usages. Subsequently, chaos phenomenon is introduced to reflect the stochastic smelting process of EAF, and the practical simulation model is established. Finally, improved genetic algorithm is used to identify the model parameters based on practical measured data. The results show that the model can effectively and accurately reflect the characteristics of different types of electric arc furnaces.
