Method to control angular speed of wind turbine rotation with vertical axis Method to control angular speed of rotation of a wind turbine with a vertical axis, in which blades of the wind turbine during change of which are radially moved, varying distance between the blade and the axis of wind turbine rotation, during hurricanes they forcedly move the blades closer to the axis of rotation of the wind turbine. In the lower part of the wind turbine they install weights in the form of reservoirs of aerodynamic airfoil with the common centre of gravity at the axis of rotation of the wind turbine, which are filled by liquid or drained and synchronously forcedly moved along horizontal radially arranged guides, varying distance between the axis of rotation of the wind turbine and the centre of gravity of each weight. |

Operating method of wind power plant 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. |
