A method (200, 300, 400, 500) for managing a wind converter, comprising: - collecting first and second data associated with a group of first measurements and a second measurement of the wind converter, respectively, wherein a causal relationship is present between said first and second measurements; - obtaining an association between the group of first measurements and the second measurement of the wind converter, when the wind converter operates in normal conditions, wherein obtaining said association includes: - selecting a reference association between a group of first measurements and a second measurement of a reference wind converter; and - obtaining the association by modifying the reference association based on at least one of: - types of the wind converter and the reference wind converter; - geographic locations of the wind converter and the reference wind converter; and - operation period of the wind converter and the reference wind converter; - determining a condition of the wind converter based on a comparison of the collected first and second data and the obtained association, the association being used as a standard for determining the condition of the wind converter; wherein determining a condition of the wind converter comprises: - generating (436, 510) an estimation of the second data based on the association and the collected first data; and - determining the condition of the wind converter based on a difference (420, 520) between the estimation of the second data and the collected second data. - collecting first and second data associated with a group of first measurements and a second measurement of the wind converter, respectively, wherein a causal relationship is present between said first and second measurements; - obtaining an association between the group of first measurements and the second measurement of the wind converter, when the wind converter operates in normal conditions, wherein obtaining said association includes: - selecting a reference association between a group of first measurements and a second measurement of a reference wind converter; and - obtaining the association by modifying the reference association based on at least one of: - types of the wind converter and the reference wind converter; - geographic locations of the wind converter and the reference wind converter; and - operation period of the wind converter and the reference wind converter; - selecting a reference association between a group of first measurements and a second measurement of a reference wind converter; and - obtaining the association by modifying the reference association based on at least one of: - types of the wind converter and the reference wind converter; - geographic locations of the wind converter and the reference wind converter; and - operation period of the wind converter and the reference wind converter; - types of the wind converter and the reference wind converter; - geographic locations of the wind converter and the reference wind converter; and - operation period of the wind converter and the reference wind converter; - determining a condition of the wind converter based on a comparison of the collected first and second data and the obtained association, the association being used as a standard for determining the condition of the wind converter; - generating (436, 510) an estimation of the second data based on the association and the collected first data; and - determining the condition of the wind converter based on a difference (420, 520) between the estimation of the second data and the collected second data.
