| Abstract |
The interest about offshore wind farm (WF) has increased significantly during past years. Usually, localdistribution is achieved by an AC grid. For distance higher than 100 km, HVDC (High Voltage DirectCurrent) connection is used for power distribution from farm to shore. Considering the recent improve-ments of DC-DC converters and theirs impact on electrical architecture, the generalization of DC linkwithin the distribution scheme of the farm becomes easier and really interesting. In this paper, a windfarm topology is under study as well as different possible control strategies for converters. EspeciallyDC-DC converter in WT and in offshore platform. Firstly, several control strategies for offshore windfarm will be studied. Then, a global comparison of the different technical solutions has been done interms of :- advantages and drawbacks for each control strategy,- possible technological choices resulting from control scheme.Finally, a comparison about the control strategies for DC-DC converters for a wind farm topology isachieved by simulating Real-Time Simulations. Full-Bridge technology for DC-DC converter appearsto be a suitable solution given it has a simple control mode, and less expensive technology than DoubleActive Bridge DC-DC converter. |
