Title: DC high voltage connection systems for offshore wind turbines
Authors: Colino, Sergio
Abstract: Renewable energies have been taking an important role in the disperse generation in the last years. Within these resources one of the most important and developed is the wind turbine technology. This work investigates a basic and robust system that could be suitable to use in applications where wind turbines are connected to a DC link. Then, it could be possible to increase the efficiency of each wind turbine system and save costs in the transformer platform at the output of the wind farm. Here a system consisting of a 2 MW Permanent Magnet Synchronous Generator (PMSG), a diode rectifier and a boost converter is analysed. The studies carried out in this project are based on simulations made with MATLAB Simulink. Considering an output voltage of 6.75 kV, the results shown that is possible to implement this system to increase the efficiency of each individual wind turbine and, as an advantage due to the DC link, have more control on the voltage levels and the output power that is supplied. Also, the losses through the components of the system were found to be small.
