Arc furnace load modeling and its impact on power grid

As a typical nonlinear impact load,the arc furnace has brought great challenge to the power grid quality management.Therefore,the analysis of arc furnace load access to power grid can effectively formulate management measurements,strengthen the power grid safety in production and improve the economic benefits.Firstly,the load characteristics of arc furnace are classified and analyzed;qualitatively described the characteristics of arc furnace load.Then based on the electric arc furnace energy balance equation and its physical mechanism of the internal chaos phenomenon,through respectively setting up the static mathematical model and dynamic model,under the condition of Simulink;quantitatively simulated the electric arc furnace.Based on the model analysis and combined with the data of typical arc furnace load access to Xianning Power Grid,the validity of the model of electric arc furnace is verified;and some relevant conclusions are given.
