摘要
提出将统一潮流控制器(Unified Power Flow Controller)应用于炼钢交流电弧炉的柔性供电方法,基于SPWM控制技术用PI控制方法设计了控制系统。利用MATLAB仿真软件,在三相非线性时变电弧阻抗模型的基础上,构建含UPFC的电弧炉供电系统模型。仿真结果表明,该方法能有效抑制电弧炉引起的电压波动与闪变,改善供电系统电能质量。
A flexible power supply method for arc furnace is presented in which UPFC is used , the control system based on the SPWM technology and PI control is adopted. Furthermore , based on the non-linear timevariable resistance model , the power supply system model with UPFC for arc furnace is established and the simulation study is made by means of Matlab software .The results show that the method is effective to decrease power voltage fluctuation , flicker and improve the power supply quality.
