Abstract

The article gives the results of experimental studies on the influence of 6DSP-40 arc steel-making furnace on the distortion of a voltage sine wave at the connection point of the furnace to the mains. The authors give the detailed description of the process of metal melting and electric mode kept during the melting process. The determination of the number of voltage harmonic components was carried out by the AR.5M analyzer of electric power quantity and quality produced by Spanish firm «Circutor». The authors considered the influence of the arc steel-making furnace (ASF) mode on the value of total voltage harmonic components at the point of connection of the ASF to the mains. The article presents the results of experimental investigations of harmonic voltage at the 10 kV busbars of MSDS feeding 6DSP-40 with the capacity of 15 MVA at Sk = 282 MVA. The experiment showed that the total of harmonic voltage components reaches the maximum values during the process of wells melt-through. The authors carried out the inspection of conformance of the voltage harmonic components and the total voltage harmonic components to the GOST 32144-2013 standard. The inspection was carried out using the PowerVision software delivered with the   electro-analyzer. It is found that the excess of limit values (c. 4.2.4.1 of GOST 32144-2013 standard, enumeration b) occurs on twenty of twenty nine harmonic components where the measurements were carried out. Within the spectrum of the voltage harmonic components the 5th, the 3rd and the 2nd harmonic components have the highest values. The maximum value of total coefficient of voltage harmonic components does not exceed 8% established by the standard for this voltage class.
