| Abstract: | Arc furnace is one kind of main harmonic sources in power systems. Because of random nature of its operation and absence of suitable ma- thematics model,it is very difficult to make a simulation study with com- pater on operation process and harmonic analysis of arc furnace,In this paper,an equivalent mathematics model of alternating arc is presented at first and then the model is improved according to the specific working conditions of arc furnace and the arc models of different operating state are obtained.The state equation of electric system of arc furnace is therefor deduced.The intention of the paper is to make a fundamental theoretical study in simulation of arc furnace for harmonic analysis. |
