Abstract :
A 5MW direct drive offshore wind turbine generator was designed and simulated using Vector Fields OPERA. This software allows calculation of the flux density, force, torque, and eddy currents in the machine at different rotor positions. Based on the data obtained from the model, initial assumptions could be validated. The selection of the type of generator was based on comparing different types of synchronous generators. Advantages and disadvantages are discussed with respect to the specified requirements, as well as different materials which will define the different parts of the generator. Arguments for the suitable machine are listed and the modelling process presented. The model of the generator is improved by changing designing parameters (position of the magnets or adding additional I-Cores) and analyse the effect of it.
