Systems and methods for damping the oscillations of a wind turbine tower

摘要

A method for damping the displacement of a wind turbine tower (104) include a processor (113) controlling at least a shock absorber (216) (e.g. an hydraulic cylinder) acting on a first beam (222) between a plurality of surfaces (e.g. 226, 228) inside the wind turbine tower.
In different embodiments the processor can also acts on valves or pistons controlling the flow all through containers (452, 454) in a water tank (352).
