STUDY OF THE FEATURES OF SIMULATION MODELING OF ELECTRICAL NETWORKS IN THE PRESENCE OF GEOMAGNETIC INDUCED CURRENTS

An analysis of methods aimed at accurate modeling of electrical networks during geomagnetic disturbances was performed. The features of the use of software environments for modeling electric power systems when lowfrequency induced currents occur in main networks are studied. The advantages and disadvantages of various methods to the calculation and modeling of geomagnetic induction currents are determined.
