FIELD: electric power engineering.
SUBSTANCE: invention relates to the field of electric power engineering, and can be used in electric power systems with wind generators. The method implements the control of an electric power system with wind generators operating for an external electrical network with a load and sources. The frequency at the output of wind turbines is set equal to the frequency of the external network. The power output from each of the wind turbines to the network is measured, the measurement results are sorted according to the power level, and the average power is calculated. The wind turbines whose power is lower than the calculated average power by a value exceeding the setpoint are determined. The phase shift is set ahead of the mentioned wind turbines with a power lower than the calculated average power by a value exceeding the setpoint. The value of the leading phase shift is set in proportion to the difference between the calculated average power and the measured power value. The actions are repeated with a time delay. The capacities are aligned.
EFFECT: uniform loading of wind turbines is ensured.
