简述了中频炉的工作原理和谐波对电力系统的危害,分析了其整流装置的谐波电流,给出了河南金汇钢厂中频炉谐波电流和电压的实测数据.由于中频炉的谐波特征比较明显,各次谐波电流含量也比较稳定,可以采用在整流变压器低压侧安装单调谐滤波器和高通滤波器相结合的无源滤波装置来进行谐波治理.此外,为了减少中频炉谐波对电网电压的影响,建议大功率中频炉在接入电网时,还要尽可能地选择短路容量较大的公共连接点.
- 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.
