摘要
A method for identifying the main frequency power train of a wind turbine. It comprises steps in real time: a) obtaining an input signal (r) of the generator speed (og {}); b) filtering said input signal (r) to obtain a signal generator speed (r1) in an appropriate band to represent the signal swing (or) comprised therein; c) extracting the primary frequency (f) of the power train of said filtered signal (r1). The invention also relates to a method of vibration damping power train of a wind turbine comprising steps of fixing the torque reference generator (Tr {sub, ref}) based on the generator speed ({og }) and the main frequency power train unit (f) identified by said method and a control system of a wind turbine implementing it.
