Wind turbines continue to be actively used to this day. At the same time, active work is being done to improve wind generating complexes and increase the efficiency of converting wind energy into electricity. One of the ways to increase the efficiency of conversion of wind energy into electricity is to magnetize the generator with permanent magnets by a third-party static capacity. A mathematical model has been developed to estimate the value of the capacitance that must be connected to the stator winding of the generator depending on a number of conditions: the size and nature of the load; parameters of the electric generator; increasing the voltage on the clamps; increasing the active power at the output of the generator. According to the results of the calculations, an expression is obtained that allows to estimate the required value of the capacity at a purely active load. For the power range of the electric generator from 0 to ≈</em><em>Рн</em><em> the value of capacity which needs to be connected to a winding of an armature of the electric generator with permanent magnets makes 4,3</em> <em>–</em> <em>32,1 uF. This provides a voltage at the terminals of the generator ≈Un with an error of ± 5%. When using an additional magnetizing capacity to increase the active power of the generator, there is an increase in power at the level of 10–15%. This is due to the increase in voltage at the generator terminals.</em></p> <p><em>The results of calculating the required value of the external capacity of the generator confirm the adequacy of the developed model and the reliability of the results, which allows to use this model for further research and evaluation of methods and means to improve wind energy conversion efficiency.
