| Abstract: | Electric arc furnace of high-power produces a large number of low order harmonics current,which will not only cause three-phase load to be unbalanced,but also lead the electrical network to fluctuate.Furthmore,it seriously influences the normal operation of devices in power system.To solve this problem,the harmonic filter and VAR compensation have been carried out.The principle of the harmonic suppression and VAR compensation has been introduced;it bases on the present situation of 35kv power supply system,... |
