Abstract
Condition-based monitoring functionality using sensors that monitor wind turbine component movement. A main shaft flange displacement sensor system can be used to provide signals used to perform fatigue assessment of the wind turbine rotor blades as well as drive train components. Output signals from the main shaft flange displacement sensor system are used to perform fatigue assessment, failure trending, diagnostic analysis, etc.
Claims20
A wind turbine comprising:
- a sensor coupled to detect movement of a wind turbine component from a base position and to generate one or more signals indicating the movement;
- and
- a control circuit coupled with the sensor to receive the one or more signals indicating the movement, to perform a condition-based monitoring operation based on the one or more signals and to selectively generate an output signal based on the condition-based monitoring operation, wherein the condition based monitoring operation comprises at least rainflow fatigue assessment.
A method comprising:
- receiving signals from a sensor indicating movement of a wind turbine component;
- performing condition-based monitoring analysis of the wind turbine component using the sensor signals, wherein the condition based monitoring operation comprises at least rainflow fatigue assessment;
- and
- generating an output indicating results of the condition-based monitoring analysis.
An article comprising a computer-readable medium having stored thereon instructions that, when executed, cause one or more processors to:
- receive signals from a sensor indicating movement of a wind turbine component;
- perform condition-based monitoring analysis of the wind turbine component using the sensor signals, wherein the condition based monitoring operation comprises at least rainflow fatigue assessment;
- and
- generate an output indicating results of the condition-based monitoring analysis.
