Abstract
A big challenge in the Wind Power industry is the breakdown of gearboxes. To
increase the knowledge about Wind Power and gearbox breakdowns Vattenfall has
done measurements on both the mechanical and electrical system of a wind power
turbine e.g. during full load and partial load. In this Master Thesis focus is on voltage and current measurements on the generator conductors and the measurements of the rotor speed. Different run scenarios for a wind power turbine have been studied and analysed briefly. Secondly a mathematical model in MATLAB/Simulink has been built, which calculates a corresponding mechanical torque based on the electrical measurements. To further improve the results from the model, more accurate speed measurements have... (More)
