FIELD: engines and pumps. ^ SUBSTANCE: invention may be used for power supply of autonomous consumers. Method includes transformation of windwheel energy with uncontrolled angle of wings installation into electric energy, its accumulation in accumulator battery, DC inversion into AC with further supply to consumer. The angle of wings installation is calculated for rated rotation frequency of windwheel. In process of operation at wind speeds that differ from design speed, rated frequency of windwheel rotation is stabilized under load, for that purpose windwheel is able to automatically control coefficient of wind energy extraction with the help of electrodynamic braking of generator by accumulator battery charging current, by rated value of which capacitance of accumulator battery is selected. Battery voltage is accepted by means of experimental selection of accumulators number in battery, which provides for rated frequency of windwheel rotation. ^ EFFECT: increased efficiency, reliability and durability of wind-electric station operation, and also expansion of used wind speeds range. |
