description: The theme of the final qualification work: "The choice of settings for protective equipment in a 0.4 kV network, taking into account the shunting effect of asynchronous electric motors". This work is devoted to the study of the phenomenon of the shunting effect of asynchronous motors in networks up to 1000 V the formation of an understanding of the occurrence criteria and the formulation of recommendations for taking this phenomenon into account when choosing the settings of protection devices. Tasks that were solved during the study: Study of modern protection devices used in networks up to 1000 V, their features, areas of application and selection requirements. The study of such a phenomenon as the shunting effect of asynchronous motors and the identification of the main criteria for its occurrence. Confirmation of the existence of SE IM by calculating the simplest scheme, which includes IM. Modeling of a complex MV system of a power plant, which includes several IMs and various groups of loads. Calculation of near and remote short circuits in the simulated system.Â Evaluation of the influence of ShE AD on the choice of protective equipment in networks up to 1000 V and the formulation of recommendations. As a result, the shunting effect of asynchronous motors was analyzed and the main criterion for its occurrence was formulated. By calculating short-circuit currents in the simplest system, the existence of SE was proved, and effective recommendations were developed and formulated for considering the shunting effect of asynchronous electric motors in 0.4 kV networks when choosing settings for protective equipment.
