FIELD: electricity.SUBSTANCE: application: in the field of electric engineering. According to the method when there is wind with speed higher than the initial speed and lower than the cut-off speed, the wind power plant supplies electric power to the mains, at that when the wind power plant operates at speed higher than the rated value or lower than the cut-off value the rotor of the wind power plant is rotated. The generator for power generation is connected to the rotor. The wind power plant has measurement instruments to measure frequency in the electric mains which are connected to the unit controlling operation of the wind power plant. The invention suggests that power generated by the wind power plant generator and transmitted to the mains is increased quickly within a short period of time beyond the current power of the wind power plant when frequency of the electric mains is lower than the preset desired value of the mains frequency.EFFECT: improving reliability.15 cl, 9 dwg, 1 tbl |
