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.PATENT REQUIREMENT 1. Device for synchronizing two or more wind turbine shaft speeds with the wind turbine generators coupled to the same supply grid, all of which minus one must be capable of speed control when the generator is connected to a supply grid, characterized in that the mill shafts are synchronized at different angles between the wind turbines, that the wings of a turbine are facing the tower at the same time. Apparatus according to claim characterized in that the angle indicators (6), (7) on the mill shafts (9), (10), which for each mill represent different angles with respect to one of the angular positions of the blades, give signals to synchronization devices (8 ) which is used to synchronize the mill shafts so that the signals from the two angle indicators coincide, ensuring that the blades of the mill are not simultaneously facing the tower. Device according to claim log2, characterized in that the turbines are coiled. Device according to claim log 2, characterized in that in a co-synchronized group of n wind turbine shafts each with A wings, the angular rotation v of the angle indicators on mill no is in relation to a wing and in relation to the rotation on mill no 1: v = 360 * (ml) / a * n 5. device according to claims 1-4, characterized in that the mill (l) in one group gets the speed controlled by different operating considerations, while the others in the group are synchronized to the mill (1). according to claims 1-5, characterized in that the control which ensures the synchronization of the mill shafts is abolished and replaced by an overall speed control when required for the safety of the mills or similar conditions such as start-up.
