Basic structure and operational principles of medium frequency furnace are introduced in this paper. The characteristics of harmonic currents produced by it are analyzed theoretically. A simulation model of medium frequency furnace with 12-pulsating reciter is set up with Matlab/Simulink. Its validity is proved for the simulation harmonic cur- rents according to the theoretical anticipation. This model could be used to predict the harmonic of medium frequency furnace not in operation. Based on this model, potential harmonic pollution of a new steel plant is studied by simulation with blatlab/Simulink.
