Claims (6)

1. Vindkraftanlæg, med en vindrotor (2), der kan drives med variabelt omdrejningstal, en generator (3), der kan drives med konstant omdrejningstal, og en elektromaskine (4), der kan drives med variabelt omdrejningstal, hvilke via et overlejringsgear (5) står i drivforbindelse med hinanden, hvor elektromaskinen (4) som kraftindstillingsindretning til omdrejningstalsregulering af generatoren (3) kan drives både som generator og som motor og via en frekvensomformer (15) står i forbindelse med et elforsyningsnet (14), hvor der i kraftflowet mellem overlejringsgearet (5) og generatoren (3) er anbragt en styrbar holdebremse (23) til låsning efter behov af generatoren (3) , kendetegnet ved, at holdebremsen (23) er udformet formsluttende aktiv.
2. Vindkraftanlæg ifølge krav 1, kendetegnet ved, at holdebremsen (23) er udformet som en klobremse med et klohjul, der er anbragt drejningssikkert på drivakslen (21), og et klohjul, der er lejret drejningssikkert på hussiden, af hvilke et af klohjulene ved hjælp af en tilordnet indstillingsanordning kan forskydes aksialt i retning af det andet klohjul.
3. Fremgangsmåde til driftsstyring af et vindkraftanlæg, som omfatter en vindrotor (2), der kan drives med variabelt omdrejningstal, en generator (3), der kan drives med konstant omdrejningstal, og en elektromaskine (4), der kan drives med variabelt omdrejningstal, hvilke via et overlejringsgear (5) står i drivforbindelse med hinanden, hvor elektromaskinen (4) som kraftindstillingsindretning til omdrejningstalsregulering af generatoren (3) kan drives både som generator og som motor og via en frekvensomformer (15) står i forbindelse med et elforsyningsnet (14), kendetegnet ved, at der ved lave vindhastigheder indrykkes en styrbar holdebremse (23), der er anbragt i kraftflowet mellem overlejringsgearet (5) og generatoren (3), generatoren (3) udkobles, og der ved hjælp af en generatordrift af elektromaskinen (4) genereres elektrisk strøm, som via frekvensomformeren (15) indledes i elforsyningsnettet (14) .
4. Fremgangsmåde ifølge krav 3, kendetegnet ved, at vindrotoren (2) ved en vindhastighed, der ligger under en startvindhastighed og over en minimal driftsvindhastighed, ved hjælp af en motordrift af elektromaskinen (4) accelereres i det mindste til opnåelsen af et minimumsomdrejningstal, og at elektromaskinen (4) i tilslutning hertil omskiftes til generatordriften.
5. Fremgangsmåde ifølge krav 3 eller 4, kendetegnet ved, at holdebremsen (23) ved en formsluttende udformning før indrykningen synkroniseres ved hjælp af en generator- og/eller motordrift af elektromaskinen (4).
6. Fremgangsmåde ifølge krav 5, kendetegnet ved, at med henblik på undgåelse af en tand mod tand-stilling på holdebremsen (23) ved roterende vindrotor (2) gennemføres synkroniseringen af holdebremsen (23) kun frem til opnåelsen af en forudbestemt minimal omdrejningstalsdifference, og ved stillestående vindrotor (2) genereres der en minimal omdrejningstalsdifference på holdebremsen (23).
