dc.description.abstractThis research paper investigates the impact of an 800 kW induction furnace on power quality within a connected power grid. The performance and lifespan of induction furnaces can be negatively affected by harmonic voltages and currents. The degree of harmonic distortion in an induction furnace is influenced by the melting load, and excessive distortion can result in the generation of higher frequencies in the power distribution system. This phenomenon poses significant challenges to power systems, including power quality issues and equipment failures. Therefore, it is crucial to closely monitor and control the level of harmonic distortion to ensure optimal system performance and longevity. In this study, power quality and its parameters are assessed following the Mongolian MNS 1778:2007 standard, which outlines twelve parameters for evaluating single-phase or three-phase 50 Hz AC power systems. However, particular emphasis is placed on the analysis of total harmonic distribution (THD) as a key parameter impacting power quality. Our analysis demonstrates that substantial distortion in the furnace current waveform can lead to THD voltages in 6/10 kV transmission lines and substations, resulting in energy efficiency losses.
