Arc furnaces can be classified as electricity receivers, which largely affect the quality of in power system. Voltage fluctuations are main disturbance generated by arc furnaces. The effects voltage include phenomenon flickering light. Apart from fluctuations, devices, to a lesser extent, source current and asymmetry, curve distortion, dips. purpose theoretical considerations is assess article ...

Due to high unit capacities, electric arc furnaces are among the receivers that significantly affect power system from which they supplied. Arc generate a number of disturbances grid, including fast-changing voltage fluctuations causing phenomenon flickering light, asymmetry, and deformation curve. The main issues discussed in article problems related distortion current waveforms, resulting ope...

The electric arc furnaces are a very large power load, determining the negative effects on the power quality (harmonics currents, unbalanced load, and reactive power). For a maximum efficiency of the power consumption it is necessary to use an automat system for control the harmonics filters, the reactive power compensation installation and the electrodes position, in order to obtain a high val...

The electric arc furnaces are a very large power load, determining the negative effects on the power quality (harmonics currents, unbalanced load, and reactive power). For a maximum efficiency of the power consumption it is necessary to use an automat system of electrodes position control, in order to obtain a high value of power factor and a maximum efficiency. In this paper is present an adap...

In electric arc furnace steelmaking units, the essential parameters are reducing price, increasing production and decreasing environmental pollution. Electric arc furnaces are the largest users of electric energy in industry. The most important techniques that can be used to reduce the electric energy consumption in electric arc furnaces are scrap preheating, stirring, use of burners and hot ch...
