摘要
根据实际交流电弧炉负荷条件和冶炼期间电弧的电气特性,建立了改进的三相非线性时变阻抗模型。该模型考虑了电弧炉控制参数、线路特征及冶炼不同阶段对电弧阻抗的影响。用Matlab实现了电弧炉模型的仿真,结果表明,提出的模型适合于研究电弧炉供电系统的电压波动。
According to the actual arc furnace condition and electric characteristic of the electric arc while smelting, sets up an improved three-phase, non-linear, time-variant impedance model. The effects of control parameters, circuit characteristics and different smelting stages on electric arc impedance are considered. Realizes the simulation of arc furnace with Matlab, and the result indicates that the model put forward is suitable for voltage fluctuates research in the electric power system of arc fumace.
