Abstract

U ovom diplomskom radu izrađen je projekt konstrukcije čeličnog stupa vjetroagregata okruglog šupljeg poprečnog presjeka.
Kao podloga korišten je danski model vjetroagregata DTU 10MW RWT. Ukupna visina konstrukcije stupa iznosi 115,6 m dok
promjer rotora vjetroagregata iznosi 178,3 m. Modeliranje konstrukcije izvršeno je u računalnom programu SCIA Engineer 21.1. Svi konstruktivni elementi proračunati su prema važećim normama Eurocode uzimajući u obzir granična stanja plastifikacije i izvijanja. Također, u radu je obrađena i mogućnosti korištenja zadane konstrukcije vjetroagregata na energetskim otocima. Energetski otoci su objekti sastavljeni od plutajućih ili priobalnih (off-shore) vjetroelektrana te pomoćnih građevina (valobran, vezovi, itd.). U ovom dijelu rada opisani su mogući načini stabilizacije plutajućeg tipa vjetroagregata. Na kraju, projektirani su priključci čeličnog nosivog sustava prema europskim normama te su prikazani nacrti konstrukcije stupa.

Abstract (english)

This thesis presents the design of the wind power plant steel structure tubular supporting structure. The Danish model of the DTU 10MW RWT wind turbine was used as a base. The overall height of the supporting structure is 115.6 m, while the diameter of the wind turbine rotor is 178.3 m. Structural modelling was performed in a computer program SCIA Engineer 21.1. All structural elements are designed according to current Eurocode standards, considering plastic and buckling limit states. Also, the thesis deals with the possibility of using this wind power plant on energy islands. Energy islands are offshore facilities consisting of floating or offshore wind power plants and ancillary objects (breakwater, berths, etc.). This part of the thesis describes possible ways of stabilising a floating type of wind turbine. Finally, the steel load-bearing system joints are designed
according to Eurocode standards, and structural drawings of the supporting structure are presented.
