The Effects Of Induction Furnace On Electric Distribution Network
Subject area: Science,Engineering and Technology · Area of research: Electrical and Electronics Engineering
Abstract
Induction furnaces are high powered electrical loads that exhibit non-linear features. They have the tendency to affect the quality of power being delivered to other loads by the electric distribution grid they are connected to; by introducing electrical power problems such as voltage sags, voltage flickers, harmonics, and so on. A three phase induction furnace was modelled using ETAP software package; and the effects of the induction furnace on the quality of electric power system supply to electricity users on the same distribution network were analysed in terms of total harmonic distortions of voltage. A passive RLC shunt filter was designed and simulated in order to mitigate these distortions caused by the induction furnace. Power flow computation was done on the network before and after the introduction of the induction furnace in order to evaluate voltage magnitude profile on the network.
Keywords
