Abstract

A device may receive historical operational data for a mechanical system, such as a rotor blade of a wind turbine. The device may determine one or more quality grades for each of one or more materials of the system, e.g., the rotor blade. The one or more quality grades may be determined by using a data model to process the historical operational data. The data model may be trained using machine learning based on one or both of historical operational data for similar systems, e.g., other rotor blades, and end-of-life (EOL) testing data for the same. The device may determine a recycling recommendation based on the one or more quality grades. The recycling recommendation may include instructions relating to recycling the one or more materials. The device may deliver the recycling recommendation to another device or recipient.

Claims (56)

1. A method of making a recycling recommendation for a rotor blade of a wind turbine, comprising:

receiving, by a computing device, historical operational data for the rotor blade;

receiving, by the computing device, historical materials data identifying composite materials of the rotor blade;

determining, by the computing device, quality grades for materials included in respective composite materials of the rotor blade, wherein the quality grades are determined by using a data model to process the historical operational data and the historical materials data, and wherein the data model has been trained using machine learning based on one or more of historical operational data for other rotor blades, historical materials data for composite materials of the other rotor blades, and historical end-of-life (EOL) testing data for the other rotor blades, wherein the quality grades for a composite material, of the respective composite materials, include a first set of one or more quality grades for a first material of the composite material and a second set of one or more quality grades for a second material of the same composite material, the first set of one or more quality grades being different than the second set of one or more quality grades;

determining, by the computing device, the recycling recommendation based on the quality grades, wherein the recycling recommendation includes a set of cut instructions indicating to separate the first material from the second material using measurement data that identifies boundaries of the first material and boundaries of the second material;

delivering, from the computing device, the recycling recommendation to a controller that provides the set of cut instructions that include the measurement data to equipment configured to perform a cutting task; and

in response to receiving the set of cut instructions, cutting, by the equipment, the composite material of the rotor blade such that the first material with the first set of one or more quality grades is separated from the second material with the second set of one or more quality grades.

2. The method of claim 1 , wherein determining the first set of one or more quality grades for the first material and the second set of one or more quality grades for the second material, comprises:

providing the historical operational data and the historical materials data as input to the data model to cause the data model to output a first expected reusability score for the first material and a second expected reusability score for the second material,

determining a first quality grade for the first material based on the first expected reusability score, and

determining a second quality grade for the second material based on the second expected reusability score.

3. The method of claim 2 , wherein the first expected reusability score and the second expected reusability score are based on at least one of:

an expected residual strength of the material,

an expected structural integrity of the material, or

expected end-of-life (EOL) fiber lengths of fibers associated with the particular material.

4. The method of claim 1 , wherein the EOL testing data includes reusability scores for materials of the other rotor blades, and wherein respective reusability scores represent a degree to which a material or a portion of that material is reusable.

5. The method of claim 1 , wherein the historical materials data includes measurement data identifying boundaries of components of the other rotor blades and data identifying boundaries of the materials included in the respective composite materials, and wherein the data model is trained to associate each respective boundary and/or subset of a boundary with a reusability score.
