摘　　要：在各种建模方法的基础上,参考电弧炉V-I特性曲线拟合法改进思路,对实际的直流电弧炉系统提出了详细的建模方案,并结合现场实际情况,建立了直流电弧具体模型。为验证模型准确度,对直流电弧炉系统进行了仿真分析。结果表明:建立的模型较好的模拟了实际的直流电弧炉系统运行,其模型误差度仅在5%左右,建模方案是有效的。On the basis of various modeling methods and improved thought of electric arc furnace V-I characteristic curve fitting method,a detailed modeling project for the practical DC electric arc furnace system is advanced.In the light of field situation,a DC electric arc furnace model has been established.To verify the model precision,the simulation analysis of this arc furnace system is carried out.The results show that the established model simulates well operation of the actual arc furnace system.And the model error rate can be kept 5% or so.Thus the modeling project is effective.
