Device for accumulating inertial energy to control and/or stabilize energy production of wind turbine, has inertia flywheel whose weight is partially compensated by differential ascending compressive force

摘要

The device has an inertia flywheel (2) assembled in rotation relative with a frame around a fixed rotational axle (3). Exposure units expose a face (4) of the flywheel to gas pressure applied to an opposite face (5) of the flywheel. Differential ascending compressive force partially compensates the weight of the flywheel. A thrust roller bearing (10) is located below the flywheel in the event of failure of a levitation system.
