| 摘 要： | 交流电弧炉是一种不平衡、非线性、时变负载,在炼钢过程中其电流会产生非正弦畸变和各次谐波,使得电网电能质量变差,通过对电弧炉电气系统的谐波分析,有利于采取合适的谐波抑制措施,改善电网电能的质量.本文采取在MATLAB 6.5/Simulink环境下搭建交流电弧炉系统仿真模型的方法,通过仿真对电弧炉电气系统进行谐波分析.仿真结果表明,电弧炉的谐波电流成份主要为2～7次,与实际系统频谱分析仪实测的结果定性性质一样.

| Abstract: | The alternating current arc furnace is an unbalanced,nonlinear and time-variant load that produces higher-order harmonics during the steel-making process.The harmonics affect the quality of electric energy in public supply network.Harmonic analysis on arc furnace electrical system is beneficial to adopt the good measure to restrain the harmonics.This paper builds the simulation model of alternating current arc furnace on the basis of the mathematical model of arc resistance by making use of power system blo... |
