Claims (8)

1. Fremgangsmåde til styring af udgangseffekten fra en vindenergiinstallation til et forsyningsnet (7) med en foreskrevet nominel frekvens (fN), hvor udgangseffekten (P) styres afhængigt af den gældende netfrekvens (f) i forsyningsnettet (7), således at udgangseffekten (P) reduceres, når netfrekvensen (f) overstiger den nominelle frekvens (fN), og at udgangseffekten (P) reduceres, så snart der detekteres en forøgelse af netfrekvensen (f) over den nominelle frekvens (fi\i), kendetegnet ved, at raten af reduktion af udgangseffekten (P) øges, når størrelsen af netfrekvensens (f) afvigelse (Af) fra den nominelle frekvens (fN) tiltager.
2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at - der findes mindst en tærskelværdi, som er højere end den nominelle frekvens (fN), for netfrekvensen; - reduktionen af udgangseffekten (P) er proportional med netfrekvensens (f) afvigelse (Af) fra den nominelle frekvens (fN); og - proportionalitetskonstanten i frekvensområdet mellem den nominelle frekvens (ϊν) og tærskelværdien er mindre end proportionalitetskonstanten i frekvensområdet over tærskelværdien.
3. Fremgangsmåde ifølge krav 1, kendetegnet ved, at reduktionen af udgangseffekten (P) er en ikke-lineær funktion af netfrekvensens (f) afvigelse (Af) fra den nominelle frekvens (fN).
4. Fremgangsmåde ifølge et af kravene 1 til 3, kendetegnet ved, at reduktionen af udgangseffekten (P) som en funktion af netfrekvensens (f) afvigelse (Af) fra den nominelle frekvens (fN) defineres ved hjælp afen overførselsfunktion.
5. Vindenergiinstallation, som er tilpasset således, at den forbindes med et forsyningsnet (7) med henblik på at tilføre forsyningsnettet (7) udgangseffekt (P), omfattende: - mindst en vinddrevet generator (17, 19); - en generatorelektronik (21,23); - en frekvenssensor (37, 39), som er udformet og anbragt således, at den kan måle den netfrekvens (f), der findes i forsyningsnettet (7), og afgive et frekvenssignal, der repræsenterer netfrekvensen (f); og - en styreenhed (33, 35), som er forbundet med generatorelektronikken (21, 23) med henblik på at levere et styresignal og med frekvenssensoren (37, 39) med henblik på at modtage frekvenssignalet, og som er tilpasset til at beregne styresignalet afhængigt af netfrekvensen (f), således at udgangseffekten (P) reduceres, så snart der detekteres en forøgelse af netfrekvensen (f) over den nominelle frekvens (fN), kendetegnet ved, at styreenheden (33, 35) er tilpasset til at beregne styresignalet afhængigt af netfrekvensen (f), således at raten af reduktion af udgangseffekten (P) øges, når størrelsen af netfrekvensens (f) afvigelse (Af) fra den nominelle frekvens (fN) tiltager.
