The paper developed a Simulink computer model of a small-power wind power plant (3 kW), which uses a magnetic gearbox instead of a mechanical gearbox, and also contains a synchronous generator with permanent magnets. Based on this model, calculations of related mechanical and electrical processes were carried out in two modes of its operation - start-up mode and mode of instantaneous increase in wind speed acting on the wind turbine (from 10 m/s to 14 m/s and then again to 10 m/ with). According to the results of the calculations, it is shown that in transient modes when short-term dynamic overloads occur, both rotors of the magnetic gearbox may fall out of synchronous motion for a certain period of time and then, depending on the parameters of the gearbox (as well as its other elements), the electromechanical system or reaches a certain working steady state, or loses the ability to transmit mechanical power from the wind turbine to the generator due to the rotors of the magnetic gearbox falling out of synchronism. At the same time, the stability of the wind power plant as a whole depends mainly on the value of the maximum magnetic moment of the reducer. Bibl. 13, Fig. 8.
