The project goal is to use Galileo’s GNSS accuracy to measure structure deflection. This is increased using differential positioning and by locating Galileo encoders on designated parts of the structure based on its particular use for wind turbines. With 362 TWh generated in 2018, wind power covered 14% of the EU’s electricity demand and accounted for 18.8% of the EU’s total installed power generation capacity. That year, there was 189 GW of installed wind power capacity in Europe: 170 GW onshore and 19 GW offshore. Wind turbine blade and tower deflections are measured using Galileo to calculate blade and tower loads, which increases energy capture and reduces main component loads.
GNSS receivers will be installed along the blade span (stations) to measure the blade deformation with five-centimeter precision and calculate the blade loads at the main blade station using a finite element model (FEM) as Ansys or direct experimental data from a blade test bench. As a reference, the maximum blade tip deflection can be up to seven meters for modern wind turbines. The solution is intended for individual wind turbines and control optimisation for entire wind farms.
