The invention relates to electric power and can be used to study power systems in different modes of operation. The required technical result consists in expanding the functionality provided by a device containing a group of four tires fitted with means of connecting the measuring means digital-to-analog recorders, as well as the capacitive load and the inverter configured to connect to corresponding contacts of the first bus, wherein, a group of electric power generators configured as a thermal power station generator, equipped with three identical power units connected to the lane howl bus through respective modular transformers, generators of nuclear electric power station, connected through a respective transformer to the second bus, hydroelectric generator, connected through a respective transformer to the third bus, and generator-equivalent of concentrated energy systems, connected via an appropriate transformer to the fourth bus, and a group of power lines It is in the form seven transmission lines, wherein the first and second transmission lines are connected between the first and WTO oh tires, a third transmission line connected between the second and third buses, the fourth and fifth transmission line connected between the first and third buses, the sixth transmission line connected between the third and fourth buses and the seventh transmission line connected between the first and fourth buses. 1 yl.
