METHOD FOR INCREASING THE INSTALLED CAPACITY COEFFICIENT OF A WIND FARM Russian patent published in 2021 - IPC F03D9/17 F16H39/02 

FIELD: wind power engineering.

SUBSTANCE: invention relates to wind power and can be used to supply electric energy to the infrastructure of rural areas in regions with low average periodic wind speeds. A method for increasing the installed capacity coefficient of a wind farm includes actuating a hydraulic pump with a wind drive, pumping hydraulic fluid under pressure into a hydraulic accumulator, accumulating energy in a hydraulic accumulator, releasing hydraulic fluid under pressure from a hydraulic accumulator into a hydraulic motor, transferring working fluid through a closed hydraulic circuit. The range of operating wind speeds of wind power plants is expanded by using two or more separate wind receiving devices with different ranges of operating wind speeds, speed and wind energy utilization coefficients. Two or more hydraulic pumps are driven by a wind drive, from which the working fluid is fed through the pipeline to the hydraulic adder, the volumes of the working fluid are connected in the adder, the summed volume of the working fluid with a given pressure is directed through the pressure control valve to the hydraulic motor. If the pressure of the working fluid volume exceeds the required one, the excess volume of the working fluid goes to the hydraulic accumulator, and if there is a lack of pressure of the working fluid, the entire volume is transferred to the hydraulic accumulator, from where, when the set pressure is reached, the accumulated working fluid under pressure is fed into the hydraulic motor through a safety valve.

EFFECT: increase in the wind power plant capacity factor due to the expansion of the range of operating wind speeds by hydraulic summation and accumulation of the volume of working fluid in a hydraulic unit with a wind drive from two or more wind-receiving devices with different parameters.
