Claims (15)
1. Vindenergianlæg med en vindrotor (3), en dermed fremdrevet dobbeltfødet asynkrongenerator (4) og en omformer (5) til tilførsel af elektrisk energi til et net (9), hvor en del (51) af omformeren på generatorsiden er tilsluttet til en rotor, og en del (53) på netsiden til en stator i generatoren (4), og der er indrettet en styreindretning (6) med en omformerregulering (7), som regulerer omformeren (5) på basis af forudfastsatte netparametre, kendetegnet ved, at der er indrettet en modusselektor (72), der samarbejder sådan med omformerreguleringen (7), at denne omformeregulering kan omskiftes mellem to driftsarter, en normal driftsart og en spændingssænkningsdriftsart, ved hvilken generatorens (4) excitering i det oversynkrone område er formindsket i forhold til den normale driftsart, idet en ekstra reaktiv strøm indføres i rotoren.
2. Vindenergianlæg ifølge krav 1, kendetegnet ved, at der er indrettet en spændingssensor (44), som bestemmer den på generatorens (4) stator påtrykte spænding og samarbejder sådan med modusselektoren (72), at generatorens (4) excitering afhængigt af statorspændingen er formindsket.
3. Vindenergianlæg ifølge et af de foregående krav, kendetegnet ved, at der i spændingssænkningsdriftsarten sker en regulering af rotorspændingen til en indstillelig lavværdi.
4. Vindenergianlæg ifølge krav 3, kendetegnet ved, at modusselektoren (72) samarbejder med en indretning til bestemmelse af ønskeværdien (71), hvilken indretning bestemmer lavværdien i afhængighed af spændingen på netsiden og/eller af netfrekvensen.
5. Vindenergianlæg ifølge et af de foregående krav, kendetegnet ved, at der er indrettet et ekstra omskiftemodul (73) for vekselretteren (53) på netsiden, som bringer denne ind i en under-, neutral- eller overexciteret driftsart.
6. Vindenergianlæg ifølge krav 5, kendetegnet ved, at det ekstra omskiftemodul (73) er udformet til med henblik på maksimal sænkning af rotorspændingen at bringe vekselretteren (53) på netsiden ind i den underexciterede driftsart.
7. Vindenergianlæg ifølge et af kravene 5 eller 6, kendetegnet ved, at det ekstra omskiftemodul (73) er forbundet sådan med et kompensationsanlæg (90), at dette kompensationsanlæg understøtter vekselretteren (53) på netsiden.
8. Fremgangsmåde til regulering af et vindenergianlæg med en af en vindrotor (3) fremdrevet dobbeltfødet asynkrongenerator (4), som med en omformer (5) tilfører elektrisk effekt til et net (9), hvor der er indrettet en styreindretning (6) med en omformerregulering (7), som regulerer omformeren på basis af forudfastsatte netparametre, kendetegnet ved omskiftning mellem en normal driftsart og en spændingssænkningsdriftsart, ved hvilken exciteringen af den dobbeltfødede asynkrongenerator (4) formindskes i forhold til den normale driftsart, idet en ekstra reaktiv strøm tilføres til en rotor i asynkrongeneratoren (4).
