摘要
为电弧炉系统谐波分析提供了一种新思路,在理论上作了研究,并用实例证明了它的可行性。首先根据电弧电阻的随机性公式,用Matlab仿真得出电弧电阻随时间变化曲线,再用对实际电弧炉系统进行仿真和谐波分析,最终得到电弧炉系统的各次谐波含量,与实际数据比较,误差较小,因此认为此方法是可行的。
A new idea for harmonic analysis of arc furnace system is put forward with theoretical research, and its feasibility is testified with examples. At first, a performance curve of arc furnace resistance is obtaind by Matlab simulation according to random variation equation of arc resistance. And then, simulation of overall system and harmonic analysis are carried out based on ultimate value of arc resistance. Finally, simulation results and actual measurement data are compared, and the error is very little. So this theory is feasible.
