Estimation of stochastic characteristics of an AC electric arc furnace
Electric Arc Furnace (EAF) is productive equipment used to melt scrap, but also injects harmonics into the utility. In this paper, the stochastic characteristics of an EAF over three complete heats were estimated at a basic sampling period. Characteristics including stationarity, normality and correlation are investigated. Besides, several statistic parameters such as mean value, standard deviation and accumulative probability were all assessed by varying sampling period. This estimation work was implemented by a microcomputer-based instrumentation system. Test results of a typical AC EAF were and discussed. They can be useful reference for the improvement of electric power quality.
