Abstract

Det er beskrevet et system for utjevning av kraft fra en turbin, hvilken turbin innbefatter minste et turbinblad (1) forbundet med et roterende nav (2), hvilket roterende nav (2) er anordnet til å drive en generator (5), kjennetegnet ved at generatoren er en flere pols synkron generator (5) forbundet via et mangfold galvanisk isolerte tre-fase kabler (11) til en flernivå frekvensomvandler (25), hvilke generator (5) er anordnet til å mate strøm til frekvensomvandleren (25) gjennom tre-fase kablene (11), hvilken flernivå frekvensomvandler (25) utgjøres av et mangfold elementer anordnet i kolonner og koblet i fallende rekkefølge for tilførsel av invertert spenning, en transformator (12) er forbundet med flernivå frekvensomvandleren (25) og er anordnet til å omdanne den tilførte inverterte spenningen til et strømnett (14) nivå forbundet med transformatorens (12) sekundærside. Det er også beskrevet en vindpark bestående av minst en selvstartende vindturbin og minst en ikke-selvstartende vindturbin, samt en fremgangsmåte for å starte minst en ikke-selvstartende vindturbin (21) med minst en selvstartende vindturbin (20) i en vindpark.
