摘要
通过将电弧炉的非线性时变电阻模型、波动性模型以及混沌模型线性叠加,在多个原有电弧炉模型的基础上建立了可以根据实际情况和个人需求进行任意调节的综合电弧炉模型,此模型通过参数设计可以表现出电弧炉各方面的特性,通过调节还能够突出表现电弧炉某一方面的特点。应用有源电力滤波器,对所提出的综合电弧炉模型进行了谐波抑制等电能质量方面的改善。应用matalb软件进行了仿真,结果表明理想有源电力滤波器基本可以保证电弧炉不对电网电能质量造成任何影响。
Through linear superposition of nonlinear time-varying resistance model, flucmating model and the chaotic mode of arc furnace, a comprehensive arc furnace model has been established based on the o adjusted according to the actual characteristics of the arc furnace riginal models of the arc furnace. This model can be freely situation and individual demand. The model can show the by parameter design and can highlight the characteristics in a certain aspect of the arc furnace by adjustment. The improvement is made on suppression of harmonic of the comprehensive arc furnace model by the active power filter （APF）. The emulation is conducted by means of matalb software. The results show that the ideal APF can basically guarantee the grid power quality not impacted by the arc furnace.
