Claims (14)
1. Vindmølle (1) til effektproduktion med en effektproducerende enhed og en rotor med et antal vinger (3), hvor vingerne (3) til styring af vindmøllens udgangseffekt (1) kan pitches ved hjælp af et vingepitchjusteringsmiddel (7), og en pitchreguleringsenhed (9) til styring af vingepitchjusteringsmidlet (7), hvor der er tilvejebragt et belastningsbestemmelsesmiddel (10) til bestemmelse af vingebelastningen ud fra vingernes pitchaktivitet (3), hvor høj pitchaktivitet indikerer høje vingebelastninger, og lav pitchaktivitet indikerer forholdsvis små vingebelastninger.
2. Vindmølle ifølge krav 1, hvor belastningsbestemmelsesmidlet (10) er indrettet til at bestemme pitchaktiviteten ud fra et pitchreferencesignal og/eller standardafvigelsen af pitchreferencesignalet og/eller den gennemsnitlige pitchhastighed og/eller den totale pitchbevægelse pr. tidsrum.
3. Vindmølle ifølge krav 1 eller 2, hvor belastningsbestemmelsesmidlet (10) er indrettet til at modtage og behandle rotorhastighedsindgangssignaler fra en rotorhastighedsbestemmelsesindretning (12) og/eller rotorreferenceha-stighedssignaler fra en rotorreferencehastighedssignalindretning (13).
4. Vindmølle ifølge et af de foregående krav, hvor belastningsbestemmelsesmidlet (10) er indrettet til at tage højde for mindst et eksternt parameter og/eller mindst et internt parameter i forbindelse med bestemmelsen af vingebelastningen.
5. Vindmølle ifølge krav 4, hvor det eksterne parameter er vindhastighed og/eller omgivelsestemperatur og/eller omgivelsestryk og/eller lufttæthed, og det interne parameter er temperatur og/eller tryk fra en hydraulikolie i vingepitchjusteringsmidlet (7) og/eller produceret effekt fra vindmøllen (1).
6. Vindmølle ifølge et af de foregående krav, hvor belastningsbestemmelsesmidlet (10) er indrettet til at generere og afgive et effektreferencestyresig-nal til den effektproducerende enhed, hvor effektproduktion udføres afhængigt af effektreferencestyresignalet, og/eller et pitchreferencestyresignal til pitchstyreenheden (9), hvor pitching af vingerne (3) udføres afhængigt af pitchreferencestyresignalet.

Fremgangsmåde til drift af en vindmølle ifølge et af kravene 1 til 7, omfattende: - bestemmelse af vingernes pitchaktivitet, - bestemmelse af vingebelastningen ud fra pitchaktiviteten under anvendelse af belastningsbestemmelsesmidlet, hvor høj pitchaktivitet indikerer høje vin-gebelastninger, og lav pitchaktivitet indikerer forholdsvis små vingebelastnin-ger, og - styring af den effektproducerende enhed og/eller rotorhastigheden afhængigt af vingebelastningen.
9. Fremgangsmåde ifølge krav 8, hvor pitchaktiviteten bestemmes ud fra pitchreferencesignalet og/eller standardafvigelsen af pitchreferencesignalet og/eller den gennemsnitlige pitchhastighed og/eller den totale pitchbevægel-se pr. tidsrum.
