The main objective of this end of degree project relies on applying a scaling methodology to a reference 15 MW wind turbine in order to reach a capacity of 20 MW. This reference wind turbine has been defined by the International Energy Agency (IEA), although it has not yet been physically installed. In addition, it has been essential as a reference model for structural and aerodynamic analyses.
Owing to the involvement in the community forum of the National Renewable Energy Laboratory (NREL) of the United States, it has been possible to acquire extensive knowledge on the analysis of the scaling of wind turbines. This forum has enabled the formulation of technical questions about wind turbines, seeing practical examples, and to appreciate experiences from other researchers in the field of wind energy, which has been essential for the progress of this undergraduate thesis. Throughout the project, it is discussed how this resource has been used to solve doubts about wind turbines, especially in areas such as structural dynamics and aerodynamic analysis.
This end of degree project presents the results obtained from simulations conducted in OpenFAST software for both wind turbine models, focusing especially on relevant parameters for aeroelastic analysis. The simulations were performed over a range of turbulent wind speeds, from cut-in (3 m/s) to cut-out (25 m/s). The results obtained using OpenFAST significantly enhanced the understanding of wind turbine parameters. OpenFAST was adopted in this project after becoming familiar with its predecessors, which are Fastv7 (7th version) and Fastv8 (8th version).
The key OpenFAST modules that have been employed are the following: ElastoDyn for structural dynamics, InflowWind for wind characterization, Aerodyn for aerodynamic modeling, and ServoDyn for electrical and control aspects. Although the controller design was beyond the scope of this research, ServoDyn was fundamental for analysing and adjusting parameters such as power, torque, and generator speed. Moreover, owing to the use of Python, all parameter results are reflected through time series and as a function of wind speed.
On the other hand, a detailed structural analysis of both wind turbines is included, calculating their natural frequencies and eigenmodes with the help of specialized software such as Modes and BModes. Finally, a comparative visualization of both wind turbines was conducted using the FastTool software from MATLAB
