Comparative Study for EAF's Reactive Energy Compensation Methods and Power Factor Improvement

摘要

In this paper is analyzing the current operating conditions of one electric arc furnace (EAF) in order to evaluate the best option to solve the energy consumption problem. Experimental results show that EAFs represent a substantial source of electric disturbances, such as voltage fluctuations, flicker, harmonics, and unbalance between phases. Improvement of the energetic performances of an EAF imposes a careful technical and economical analysis. The possible compensation solutions include passive filter, SVC (static var compensator) and STATCOM (static synchronous compensator). Finally, the guideline for compensator selection and performance estimation is obtained.
