Wind turbine comprising one or more blades, incorporating in each blade a damping device comprising a first damping element tuned at the main resonance frequency of the bladeΩo and K additional damping elements tuned at frequenciesΩ1,Ω2, . . .Ωk so that in the event of blade vibrations its amplitude A is reduced in a percentage Y of the amplitude Ao at the main resonance frequency of the bladeΩo in a band extended above and below the main resonance frequency of the bladeΩo in a percentage X ofΩo, said frequenciesΩ1,Ω2, . . .Ωk being comprised within said band.
