Simulation of Three-Phase Circuits with Nonlinear Load

When studying the features of electrical circuits with nonlinear elements in the course “Theoretical Fundamentals of Electrical Engineering”, students face with the problem of analytical analysis complexity. The use of software allows to optimize the learning process and consider more different options for tasks. Dynamic processes in three-phase alternating current circuits with a nonlinear load in the form of a coil with a ferromagnetic core and distinctive features of the analysis of such circuits are described. In connection with the difficulties of analytical calculations, the use of numerical analysis methods by means of the MatLab software is proposed.
