Working Condition Identification Method of Wind Turbine Drivetrain

The operation state of the wind turbine drivetrain is complex and variable, making it difficult to accurately evaluate under drivetrain’s anomalies. In order identify operating main drivetrain, a method for working condition identification proposed. Firstly, appropriate parameters are selected distinguished from feature parameters. Secondly, aerodynamic power prediction model established, which solves problem inaccurate theoretical estimation. Finally, after historical conditions classified, proposed analyzed validated by cases. results show that can conditions, avoiding influence an abnormal provide basis real-time monitoring evaluation.
