摘要
基于电弧炉的谐波电压源和谐波电流源模型原理,应用Matlab在频域内搭建了电弧炉模型,通过分析发现,此模型可以很好的应用于出电弧炉的波动性研究中。同时提出对原有应用于谐波研究的电弧炉电阻模型的改进。即将原有的电弧炉电阻公式和后来提出的能量关系综合考虑,推倒得出新的关系式,在此公式的基础上,用Matlab仿真出电弧炉电阻随时间变化的曲线。又在Matlab软件基础上,对目前研究较热的混沌电弧炉模型做了仿真,与文献给出的波形对比发现,此模型可以很好的反应实际状况。最后提出最简单,最适合工程实际的仿真方案。
Based on the principle of harmonic current and voltage source of electric arc furnace, building the electric arc furnace’s model on the software of matlab, through analysis, concluding this model shows the volatility of the electric arc furnace very well. At the same time, put forward the improvement about the resistance model of the electric arc furnace which applies to the harmonic research. This model considers the original formula about the resistance of the electric arc furnace and the later relationship between energy, through derivation, drawing a new formula, this formula lead us to draw a new curve about time-varying resistance. Then, based on the software of Matlab, gives chaotic arc furnace model, the research of this model is hot. Comparing the actual wave which was gave by literature, proving this model is reasonable. Finally, providing the most simple and suitable model for engineering scheme of simulation.
