Abstract
Due to the station transformer capacity of the wind farm is too small,the primary current value of the current transformer(CT)used for protection of station transformer is selected according to the protective checking current will cause it is difficult to set or even unable to give the secondary setting value.Combination with the protection setting calculation of station transformer,this paper proposes a method for selecting the primary current value of CT suitable for station transformerprotection.Finally,the correctness of this method is verified bysetting value of station transformer for wind farm project in operation.关键词
