| Abstract: |
| The application experience of inductive filtering technology in industrial power system is analyzed. The single-phase equivalent circuit of inductive filtering，as well as its basic principle and technical characteristics，is introduced and its merits are analyzed. The power circuit topology of primary equipments of an operating industrial power system is shown with main technical parameters and technical characteristics. A detailed field test of power quality of industrial power system is carried out and the results indicate that，the industrial power system applying inductive filtering technology suppresses the harmonic currents at system side and decreases the AC magnetic flux of rectifier transformer core. Consequently，the additional harmonic loss of rectifier transformer is reduced，the power factor is enhanced and the power quality is improved. |
