- Abstract:
- The working principle of the intermediate frequency furnace and the harm of harmonics to the power system are briefly described, the harmonic current of the rectifier device is analyzed, and the measured data of the harmonic current and voltage of the intermediate frequency furnace of Henan Jinhui Steel Mill are given. Since the harmonic characteristics of the intermediate frequency furnace are relatively obvious and the harmonic current content of each time is relatively stable, the passive filter device combining a single-tuning filter and a high-pass filter can be installed on the low-voltage side of the rectifier transformer to carry out harmonic control. In addition, in order to reduce the influence of the harmonics of the intermediate frequency furnace on the grid voltage, it is recommended that the high-power intermediate frequency furnace should also choose a public connection point with a large short-circuit capacity as much as possible when connected to the power grid.
