摘要
介绍了中频炉的基本结构及工作原理,从理论上分析其产生的谐波电流特性.利用Matlab/Simulink仿真工具搭建了采用12脉动整流电路的中频炉仿真模型,并仿真分析其谐波电流.仿真结果符合理论预期,验证了该仿真模型的正确性,可作为未投产中频炉的谐波预估工具.基于此模型利用Matlab/Simulink对某新建钢厂供电系统进行仿真,分析其潜在的谐波污染.
Basic structure and operational principles of medium frequency furnace are introduced in this paper. The characteristics of harmonic currents produced by it are analyzed theoretically. A simulation model of medium frequency furnace with 12-pulsating reciter is set up with Matlab/Simulink. Its validity is proved for the simulation harmonic cur- rents according to the theoretical anticipation. This model could be used to predict the harmonic of medium frequency furnace not in operation. Based on this model, potential harmonic pollution of a new steel plant is studied by simulation with blatlab/Simulink.
