Abstract

Fremgangsmåte og system for kraftstyring og lastutkobling. Fremgangsmåten innbefattende trinnene: a) Beregning av en reservekraft RP som: RP = APT - APh - GPT hvor APT er en total genereringskapasitet for et antall løpende generatorer i et kraftsystem, APh er en høyeste kapasitet for en hvilken som helst av de løpende generatorene, og GPT er en generert totalstrømkraft fra de løpende generatorene, b) dersom reservekraften RP er negativ, generering av en lastutkoblingsliste som identifiserer en eller flere laster i kraftsystemet som skal utkobles i hovedsaken samtidig, slik at et totalt kraftforbruk for lastene i lastutkoblingslisten er lik eller større enn et underskudd av reservekraft RP, c) lagring av lastutkoblingslisten i en buffer, en i hovedsaken kontinuerlig gjentagelse av trinnene a) til c), og utkobling av lastene som er identifisert i den lastutkoblingslisten som er lagret i bufferen, ved detektering av en feil i en av generatorene.
