Claims (4)
1. Vindpark (100) med flere vindmøllegeneratorer (110), som er sammenkoblede med et transmissionsnet (190), idet hver vindmøllegenerator (100) indbefatter en lokal styreenhed, der anvender terminalspænding og -strøm registreret til tilvejebringelse af en passende reaktion til at foranledige, at den respektive vindmøllegenerator (110) tilvejebringer en ønsket blindeffekt og spænding, og et generatorstyringssystem, omfattende: en blindeffektregulator (240) til styring af vindmøllegeneratorens blindeffekt-produktion ved at tilpasse en spændingsindstillingsværdi til en spændingsregulator (270), hvor blindeffektregulatoren (240) har en første tidskonstant; og spændingsregulatoren (270) er sammenkoblet med blindeffektregulatoren (240) til styring af den respektive vindmøllegenerators (110) virkeeffelproduktion, hvor spændingsregulatoren (270) har en anden tidskonstant, hvor den første tidskonstant er numerisk større end den anden tidskonstant, hvor styringssystemet modtager en blindeffektkommando (155) på vindparkniveau fra en styreenhed (150) på vindparkniveau.
2. Vindpark (100) ifølge krav 1, hvor et inputsignal til blindeffektregulatoren (235) omfatter et fejlsignal, der angiver en forskel mellem en kommando, der er begrænset til et forudbestemt område, som er baseret på en generator-blindeffektkapacitet (230), og et signal, der angiver målt blindeffekt (210).
3. Vindpark (100) ifølge krav 1, hvor et outputsignal fra blindeffektregulatoren (250) er begrænset til et forudbestemt område, der er defineret af øvre (242) og nedre (244) grænser, som er baseret på generatorterminalspænding.
4. Vindpark (100) ifølge krav 1, hvor et inputsignal til spændingsregulatoren (270) omfatter et fejlsignal, der angiver en forskel mellem et outputsignal fra blindeffektregulatoren, som er begrænset til et forudbestemt område, der er defineret af en øvre og en nedre grænse, baseret på konverterens nominelle ydelse og/eller indstillede driftsværdier (250), og et signal, der angiver målt terminalspænding (255), hvor outputsignalet fra spændingsregulatoren (280) bestemmer en strøm, der skal tilføres til generatoren.
