Description

PATENTKRAV 1. Anordning ved synkronisering af to eller flere vindmølleakslers omdrejningstal med vindmøllegeneratorerne koblet til samme forsyningsnet, hvor alle minus een skal kunne hastighedsstyres når generatoren er koblet til et forsyningsnet, kendetegnet ved, at mølleakslerne synkroniseres med forskellige vinkler mellem møllernes vinger, hvorved det hindres, at en mølles vinger befinder sig ud for tårnet samtidig. 2. Anordning i følge krav lkendetegnet ved, at vinkelindikatorer (6),(7) på mølleakslerne(9),(10), som for hver mølle repræsenter forskellige vinkler i forhold til een af vingernes vinkelmæssige placering, afgiver signaler til synkroniseringsanordninger (8) som benyttes til synkronisering af mølleakslerne, så signalerne fra de to vinkelindikatorer sammenfalder, hvorved det sikres at møllernes vinger ikke samtidig befinder sig ud for tårnet. 3. Anordning ifølge krav log2, kendegnet ved, at møllerne er tovingede. 4. anordning ifølge krav log 2, kendetegnet ved, at i en sammensynkroniseret gruppe af n vindmølleaksler hver med A vinger, er vinkeldrejningen v af vinkelindikatorerne på mølle nr m i forhold til en vinge og i forhold til drejningen på mølle nr 1 : v= 360 *(m-l)/a*n 5. anordning i følge krav 1-4, kendetegnet ved, at møllen(l) i en gruppe får omdrejningtallet styret af forskellige driftshensyn, mens de øvrige i gruppen synkroniseres til møllen (1) 6. anordning ifølge krav 1-5, kendetegnet ved, at styringen som sikrer synkroniseringen af mølleakslerne ophæves og erstattes af en overordnet hastighedsstyring, når det nødvendiggøres af hensyn til møllernes sikkerhed eller lignende forhold såsom opstart.
