Özet:In order to prevent the harmful effects of Medium-Frequency Induction Melting Furnaces to the grid they are connected, it is very important to keep the unintended current harmonics generated by them within allowed limits. Since Medium-Frequency Induction Melting Furnace load contains variety of harmonics and interharmonics in a wide range, a flexible solution with no parallel resonance risk should be implemented. A Hybrid Active Power Filter is the most suitable solution for such a case. In this research work, hysteresis band control algorithm is proposed and implemented to control the hybrid active power filter. Moreover, some challenging design issues are investigated; such as, adaptive hysteresis band design, proposal of novel performance evaluation criterion, implementation of hierarchical control system architecture and the comparison of hysteresis band control with traditional methods. In addition to these design issues, the whole system is simulated and put into practice at field so that the experimental results could be compared with the theoretical ones. The experimental results prove that the proposed Hybrid Active Power Filter system effectively suppresses the most dominant harmonics and interharmonics of Induction Melting Furnace load.
