Abstract
In order to assess the flicker caused by electric arc furnace,the simulation method to assess flicker and its application in electric arc furnace power system was studied. Firstly,based on the flickermeter-functional and design specifications recommended by IEC,an IEC flickermeter was designed concretely;Secondly,an IEC flickermeter model was established in SIMULINK,and a special M file which could be used to calculate the short-term flicker sensation indicator (Pst) was compiled,according to the IEC criterion,the flickermeter model was tested;Finally,assess of the flicker caused by an actual electric arc furnace was achieved,the instantaneous flicker sensation S(t) in the point of common coupling was gained. The results show that application of simulation method to assess the flicker caused by electric arc furnace is an effective way.
