Abstract

The model and algorithm for calculation of functioning of an electric power grid of any configuration and complexity during geomagnetic storms of various intensity and duration was developed. The calculations were performed in MATLAB mathematical system and in Simulink package. Both standard blocks of Simulink and SimPowerSystems and blocks designed by the authors were used to develop the electric power grid model. Special features of the developed calculated model of the electric power grid are binding of objects to geographical coordinates of a territory; modeling the power transformers are designed on the basis of T-shaped equivalent circuit with a nonlinear mutual inductance magnetization branch which is a function of the value of geomagnetically induced current; by introduction of the source of harmonic components of magnetizing currents; calculation of RMS values of active, reactive and total power in all elements is done with regard to the impact of harmonic components of current and voltage. The results of modeling of the impact of a geomagnetic storm of various intensity with the west-east direction of the geoelectric field voltage vector for Samara region electric power grid.
