Abstract:
A wind energy system, comprising:a chimney comprising one of a decommissioned power station chimney and an industrial chimney having an upper end, a base end, and a vertical center axis, wherein said chimney comprises a reinforced concrete material;a wind converter having a rotor rotatable about a substantially horizontal rotor axis for producing an electrical output and rotor vanes mounted proximate an end of said rotor. wherein a capacity of said electrical output comprises at least 600 kW;a retaining means for supporting said wind converter; anda receiving part arranged on said chimney for rotatable supporting said retaining means such that said rotor vanes pass said chimney at a distance that prevents aerodynamic shock loads on said rotor,wherein said chimney is cut to a height at which said wind converter is supportable without causing structural overload of said chimney based on static and dynamic considerations of said chimney and a configuration of said wind converter.
