description: This work is devoted to the development of a torsional vibration damper for a wind power plant based on a synchronous generator with permanent magnets. The tasks to be solved in the course of the research are: 1. Investigation of the basic principles of variable speed wind turbines. 2. Development of the main subsystems of the wind power plant model using the Simulink software-computing complex. 3. Modeling of control systems of a wind power plant in Simulink. 4. Study of natural and forced frequencies of vibrations of parts of wind turbine, development and adjustment of damper for damping of torsional vibrations of these frequencies. 5. Testing the performance of the torsional vibration damper in case of abrupt change in wind speed. The theoretical calculation of the natural frequency of oscillations of the transmission, as well as the frequency of forced oscillations from the blades at lateral bending was made.Â It is shown that at a sharp increase in wind speed above the nominal value in the torque and angular speed of rotation of the generator rotor there are oscillations, the frequency of which coincides with the calculated value. The structure of the system of automatic regulation of the inverter on the side of the synchronous generator is developed in the work, which allows to significantly reduce the amplitude of torsional oscillations, up to their complete damping.
