Method of alarm mask generation and condition monitoring of wind turbines |
摘要 |
In one aspect, an alarm mask for condition monitoring in a wind turbine is automatically generated. A reference data selecting definition is selected from a control definition repository in the wind turbine. The reference data selecting definition specifies a time interval of recorded reference data. Reference data is selected from a sensor located in the wind turbine recorded during the time interval. A reference value is calculated based on the reference data. A first and a second alarm mask factor are selected from the control definition repository. A first alarm mask is calculated based on multiplying the first alarm mask factor and the reference value. A second alarm mask is calculated based on multiplying the second alarm mask factor by the reference value. |
