In large steel enterprises, high-power electrical equipment such as motors and electric furnaces, especially large-scale frequency conversion and thyristor systems, generate a large amount of high-order harmonics, spike pulses and other power pollution, which has seriously endangered the quality of electric energy. On the other hand, the large-scale use of precision electronic equipment and computer control systems have put forward more stringent requirements on the quality of electric energy. This contradiction is becoming increasingly acute and has attracted the attention of the majority of technical personnel.
