CONTROL METHOD OF WIND-DRIVEN POWER PLANT, AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC F03D7/02 

FIELD: power industry.

SUBSTANCE: control method of wind-driven power plant is characterised by the fact that signal on wind velocity at the height of wind wheel rotation axis; signal for adjusting the common setting angle of windwheel blades and signal on setting angle of each windwheel blade is shaped; as well as signal of angular position of windwheel wheel shaft is shaped; according to these signals there additionally shaped is adjustment signal of setting angle of each blade to function of height of its position during each windwheel revolution. In addition, wind-driven power plant includes control units of blade setting angle as per the number of windwheel blades; outlet of each unit is connected to the rod of its own blade; the first, the second and the third inputs of control unit of blade setting angle are connected respectively to outputs of wind velocity sensor, setting unit of blade setting angle and angular shaft position sensor, and the fourth input of the above unit is connected to output of block of slip rings, the input of which is connected to power system.

EFFECT: increasing efficiency by increasing the used installed capacity of wind-driven power plant and electric energy generation.
