Rolling stand electric drive model regarding influence of power supply network parameters

<span lang="EN-US">Operation mode of hot rolling mill finishing group stands ArcelorMittal Temirtau JSC electric drives along with thyristor converter units, intended for the supply effect significantly power network parameters. While being carried out experimental research on operating modes supplying mill, some oscillograms were constructed that indicate voltage during process. Analyzing it appears there are unacceptable drops throughout (more than 10%), that, in its turn, effects negatively main and auxiliary functioning. Electric drive simulation model have been aim accomplishment to learn more about features as well where objective is getting decreased parameters their mutual influence. The scientific project purpose verification mathematical choice correctness, construction a control system stands, taking into consideration checking adequacy.</span>
