WIND POWER PLANT Russian patent published in 1997 - IPC

FIELD: wind power engineering. SUBSTANCE: wind power plant has wind motor and device for accumulating energy that comprises hydraulic pump, fluid- pressure accumulators, hydraulic motor, and motor- electric generator. The plant is additionally provided with electric generator kinematically coupled with the wind motor and electric motor that define an electric pump unit with the hydraulic pump. The device for accumulating energy is made up as a unit of fluid- pressure accumulators the gas spaces of which are interconnected . The interconnected hydraulic spaces of the fluid-pressure accumulators are connected with the hydraulic pump through a check valve and with the hydraulic motor through valve device and converter of hydraulic pressure. EFFECT: enhanced efficiency. 2 dwg
