MATHEMATICAL MODELING AND ANALYSIS OF ELECTROMAGNETIC PROCESSES IN THE THYRISTOR CURRENT REGULATOR SYSTEM - SPECIAL TRANSFORMER INSTALLATION INSTALLATION IN BCF
Peculiarities of mathematical modeling are considered and electromagnetic processes in the system “thyristor current regulator - special transformer” (TRS-ST) are analyzed. An indirect method for measuring the temperature of a die plate, which is controlled by the primary current of the CT, is proposed. A simulation model of the TRS-ST system has been created, which makes it possible to take into account the nonlinearity of the characteristics of the transformer core material and the nonlinearity of the load resistance to achieve the required accuracy of electromagnetic processes. The results of simulation confirmed the effectiveness of the developed mathematical model as the difference between the curves of transients obtained by modeling and the curves obtained during research on the experimental setup is not more than 5% and allows to further optimize multi-loop control systems with interconnected and nonlinear parameters.
