摘　　要：为了仿真评估电弧炉引起的闪变严重度,对闪变仿真法及其在电弧炉供电系统中的应用进行了研究。先基于IEC闪变测量原理设计出闪变仪中各环节的传递函数和具体参数,再在SIMULINK环境下建立闪变仪模型并利用MATLAB语言编写专门的计算短时间闪变值Pst程序,根据IEC推荐的检验标准验证闪变仪模型的正确性和有效性,最后结合交流电弧炉随机模型,对电弧炉引起的闪变严重度进行仿真研究。研究表明运用仿真法评估电弧炉引起的闪变严重度是一种行之有效的方法。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.
