In this paper, the method of correction of network current distortion with controllable inductive power filter (CIPF) is proposed to solve the quality problems of the power available in the induction furnace load. This method is based on the equilibrium potential theory of magnetic potential combined with controlled inductive power filter technology. First, the structure of the system and the filter wiring scheme are presented, and the equivalent circuit is performed along with the mathematical models of the filtering system. A modified control strategy is then designed to achieve better filtering performance. Technical characteristics such as the elimination of harmonics due to nonlinear load and intensification damping are shown by the analysis mechanism. Finally, the simulation model of the filtering system is implemented in the Simulink environment of MATLAB software. The simulation results confirm the theoretical analysis and show that the proposed method with appropriate control efficiency can effectively eliminate the harmonics passing through the transformer and improve the distortion in the network current caused by the induction furnace load. |
