Abstract

Et vindkraftanlegg som har minst en vindmølle med fast hastighet (FS1-FS4) og minst en vindmølle med variabel hastighet (VS1-VS4) som er koblet til et felles elektrisk nett (CNET1-CNET3, EPG). Vindmøllen med variabel hastighet har et styrbart omformerorgan (10) for uavhengig styring av aktiv effekt (P) og av reaktiv effekt (Q) levert til det felles elektriske nett, avhengig av en settpunktverdi for aktiv effekt (Pset) og en settpunktverdi for reaktiv effekt (Qset). Kraftanlegget har videre måleorganer (121-125) for å tilveiebringe målte verdier (U, I) i et frekvensintervall som strekker seg over og under en frekvens på 8,8 Hz, re-presentative for enten en spenningsfluktuasjon eller en fluktuasjon i aktiv og reaktiv effekt i et valgt punkt i det felles elektriske nett. Anlegget omfatter videre sty-ringsorganer for flimmer (16, 17, 18P, 18Q) som reagerer på fluktuasjoner i nevnte frekvensintervall for å motta de målte verdier og å generere minst ett korreksjonssignal for aktivt kraftflimmer (Pcorr, Pcorr') og et korreksjonssignal for reaktiv kraftflimmer (Qcorr, Qcorr') avhengig av dette, og organer (21p, 21Q) for å motta nevnte minst ene flimmerkorreksjonssignal og for å danne minst en settpunktverdi for aktiv kraft og en settpunktverdi for reaktiv kraft avhengig av nevnte minst ene flimmerkorreksjonssignal for aktiv kraft.A wind turbine that has at least one fixed-speed wind turbine (FS1-FS4) and at least one variable-speed wind turbine (VS1-VS4) that is connected to a common electrical network (CNET1-CNET3, EPG). The variable speed wind turbine has a controllable converter means (10) for independent control of active power (P) and of reactive power (Q) supplied to the common electrical network, depending on a setpoint value for active power (Pset) and a setpoint value for reactive power (Qset). The power plant further has measuring means (121-125) for providing measured values (U, I) in a frequency range extending above and below a frequency of 8.8 Hz, representative of either a voltage fluctuation or a fluctuation in active and reactive power at a selected point in the common electrical network. The plant further comprises flicker control means (16, 17, 18P, 18Q) responsive to fluctuations in said frequency range to receive the measured values and to generate at least one correction signal for active force flicker (Pcorr, Pcorr ') and a correction signal for reactive force flicker (Qcorr, Qcorr ') depending thereon, and means (21p, 21Q) for receiving said at least one flicker correction signal and for forming at least one setpoint value for active force and a setpoint value for reactive force depending on said at least one flicker correction signal for active force .
