Abstract
Wind turbines play a vital role in producing sustainable and clean energy to fulfil the growing energy needs. Energy generated from wind turbines being more sustainable and cost effective, many countries have taken a major step to develop wind turbines with large capacity. There has been a significant reduction in the levelized cost of energy (LCOE) since the 1980’s from the development of larger wind farms and from consistent performance improvements of wind turbine components. The power generation capacity of wind turbines has increased significantly over the years with the use of taller towers. When the tower height increases, the loads on the foundation increase and the foundation becomes significantly larger. The geotechnical design of foundations for taller wind turbines has also become complicated presenting unique challenges for each location.
In this project, the economic advantages of using raft foundations, pile group foundations and piled-raft foundations are discussed based on the geotechnical design results and parametric studies using both analytical calculations and numerical simulations using GROUP and PLAXIS 3D software.
