Tower Construction Of A Wind Turbine And Method For Stabilizing A Tower Construction Of A Wind Turbine
A tower structure for a wind power plant permits very high hub heights in a cooperation of internal prestress, guying, and a torsionally rigid tower shaft. The tower structure has a tower shaft, a foundation and a transition piece in a region of an upper end of the tower shaft. Guy elements are inclined towards a longitudinal axis of the tower shaft, and extend radially outside an outer skin of the tower shaft. Tension members are radially inside the outer skin to prestress the tower shaft vertically at least in sections. The tower shaft is made of prestressed concrete in a region between the transition piece and the foundation. To control resonance behavior, prestressing and guy elements are acted upon with a variable tensile stress which varies and influences natural frequencies of the tower structure such that no interferences occur between excitation frequencies and the natural frequencies, and such that an aerodynamic absorption is also possible.
