Study Of The Software On Harmonics Analysis Of Electrical ARC Furnace Based On MATLAB

This paper mainly studies two problems: the first: analyzes the harmonics impaction in power-grids caused by electric arc furnace (EAF). The second: develops a simulation software using Matlab to analyze this impaction. The latter is the main content.Harmonics influence almost all the electrical devices and, therefore, it is always a hot study. This paper mainly studies the harmonics impaction caused by EAF. There are many hardware and software methods to deduce the harmonics in power-grids. Because of the funds and place limitation in hardware method, it is important to look for effective software method. However, the existing simulation softwares in electrical system do not have the model of EAF, it becomes an important task of this paper to develop such a software to analyze and deduce the harms caused by EAF system.
