Claims (7)

1. Reguleringsindretning til regulering af en bladindstillingsvinkel for mindst et rotorblad i et vindenergianlæg, og hvor der er indkoblet en første reguleringsgren, som har mindst en differentieringsdel indkoblet til bestemmelse af bladindstillingsvinklen, når en aktuel værdi for et generator- og/eller et rotoromdrejningstal er større end en i forvejen bestemt anden omkoblingsværdi.
2. Reguleringsindretning ifølge krav 1, kendetegnet ved, at der under en delbelastnings-drift af vindenergianlægget kan foretages en regulering af bladindstillingsvinklen ved hjælp af en anden og en tredje reguleringsgren (26, 16).
3. Reguleringsindretning ifølge krav 1 eller 2, kendetegnet ved, at en i forvejen bestemt første om koblingsværd i vedrørende generator- og/eller rotoromdrejningstallet foreligger og ved en aktuel værdi for generator- og/eller rotoromdrejningstallet er mindre end den i forvejen bestemte omkoblingsværdi ved delbelastnings-drift af vindenergianlægget.
4. Reguleringsindretning ifølge krav 1 til 3, kendetegnet ved, at en regulering af bladindstillingsvinklen yderligere kan ske ved hjælp af den første reguleringsgren, når der foreligger fuld-belastnings-drift af vindenergianlægget.
5. Reguleringsindretning ifølge krav 4, kendetegnet ved, at der kan være tilvejebragt en yderligere regulering af bladindstillingsvinklen ved hjælp af den første reguleringsgren, såfremt der foreligger en overgang fra delbelastnings-drift til fuld-belastnings-drift.
6. Reguleringsindretning ifølge et af kravene 2 til 5, kendetegnet ved, at der i den anden reguleringsgren findes et proportional-filter (28), som er afstemt efter drivstangens svingninger.
7. Reguleringsindretning ifølge et af kravene 2 til 6, kendetegnet ved, at der i den tredje reguleringsgren findes et integrationsorgan.
