Vetrenjače u Srbiji
• Savremena rešenja elektrana na vetar sve su
  brojnija na onim lokacijama i u onim zemljama
  na svetu gde postoje odgovarajući potencijali
  energije vetra.

  Na osnovu velikog broja rezultata dobijenih
  naučnim istrazivanjima i merenjima , takođe i
  kod nas postoje lokacije sa visokim
  potencijalom za izgradnju vetrenjača.
Inovativna rešenja primenjena na ovom tipu
vetrogeneratora odnose se na:
Primenu lake rešetkaste aluminijumske konstrukcije
kao glavnog dela turbine , na koju je montirana
podkonstrukcija sa pokretnim krilima izrađenim od
savitljivih PVC materijala. Ovo tehničko rešenje
bazirano na pokretnim krilima, daje mogućnost
turbini da sama određuje najpovoljniji položaj u
pravcu kretanja vetra, čime se dobija maksimalan
stepen iskorišćenja.
Primena velikog broja krila i mogućnost njihovog
izvijanja (promene pozicije u toku kretanja pri
promeni brzine vetra) preko posebnog pokretnog
mehanizma omogućava veliku udarnu površinu i
veoma ujednačen režim obrtanja turbine i rada
generatora.
Male dimenzije jezgra, postignute su prenosom
snage sa oboda turbine , gde su brzine dovoljno
velike.
Tehnologija ovog proizvoda obuhvata sve
neophodne karakteristike u cilju postizanja
maksimalnih rezultata u iskorišćenju energije vetra.
Ovo se odnosi na uslove malih i srednjih brzina
vetra kao što su u Srbiji.
Ova vetroelektrana poseduje vetreno kolo koje se sastoji od obrtnog jezgra valjkastog
oblika na kome je montirana aluminijumska rešetkasta konstrukcija, povezana i
učvršćena tankim čeličnim sajlama.
Kočnica je postavljena na obodu vetrenog kola. Pokretna krila koja se otvaraju pri većoj brzini
vetra i ojačani držači krila pružaju mogućnost da se sa glavne osovine (rotora) prenesi
snaga.

Pokretni mehanizam, kao sastavni deo podkonstrukcije omogućava otvaranje i zatvaranje
krila na zadatoj brzini vetra, promenu koraka i regulaciju broja obrtaja pri različitim
brzinama.
Krila su širom stranom trapeza montirana na periferiji turbine što daje veći stepen
iskorišćenja.
Na suprotnoj strani, krila su odmaknuta od jezgra u cilju slobodnog protoka vazduha u ovom
delu konstrukcije i sprečavanja vrtloga.

Prenos energije sa vertenog kola na generatore, vrši se zupčastim kaišom ili lancom.
Laka konstrukcija vetrenog generatora i velike površine na periferijskim delovima krila ,
uslovljavaju start vetrenog kola kod brzine vetra od 1m/s.
