Background: Wind Turbine Foundation Design

Wind turbine foundations play a crucial role in transferring the loads from the turbine and tower into the soil, ensuring stability and preventing tipping over. Traditional design methods often result in conservative designs with excessive material usage. However, at Windbase, the focus is on optimizing designs, reducing CO2 emissions, and minimizing costs while ensuring efficiency and safety.

Challenges in Wind Turbine Foundation Design

Soft soils in the Netherlands Present a challenge in wind turbine foundation design. Non-linear finite element analysis is typically used to gain optimized designs, but it comes at the cost of longer analysis times. The preliminary design phase cannot afford such a lengthy process, requiring a faster and more efficient solution.

Traditional Design Methods

Traditional design methods in wind turbine foundation design lead to conservative designs due to the limitations of analysis techniques. These methods often result in excessive material usage and higher costs. There is a need for a more advanced approach that can provide optimized designs while reducing CO2 emissions.

Data Set Establishment

The establishment of the data set is crucial for ensuring the training and validation of machine learning models. It involves identifying key design parameters and creating a dataset with consistent data structure. The dataset is then used as input features for developing the machine learning models. Windbase's database is utilized to generate over 2000 finite element models, focusing on the moment rotation behavior of wind turbine foundations.

Developing the Machine Learning Model

The development process of the machine learning model involves the usage of K-fold cross-validation to split the data set. Feature selection and hyperparameter optimization are conducted using genetic algorithms to achieve the best predictive performance. Two machine learning algorithms, random forest, and feed-forward neural network, are selected for their scalability, speed, accuracy, and interpretability.

Implementing Machine Learning in the Design Process

To make the machine learning model accessible and user-friendly, it is directly implemented into the existing design workflow. A button is added to the design process, which collects Relevant parameters and sends them to an Azure function hosting the machine learning algorithm. The algorithm calculates the key points of the moment rotation diagram and returns them to the designer. These results aid in determining the capacity and stiffness of the wind turbine foundation, leading to better designs in a matter of seconds.
