The technology associated with offshore wind farms is discussed in detail. First, the various offshore wind turbines are reviewed and the factors influencing their characteristics are outlined in comparison with their onshore counterparts. This overview serves as a basis for the discussion that follows regarding the possible electrical connection within the farm, and between the farm and the grid. Voltage-source converter-based HV DC connection is compared with HVAC connection. Finally, a novel multilevel converter-based HVDC system, based on flying capacitor multilevel converters is proposed, as a possible interface between the farm and the grid.

Doubly Fed

VSC-HVDC has become prior transmission way in delivering off-shore wind power. This paper studies offshore wind system based on DFIG (Doubly Fed Induction Generator) wind turbine. The control strategy of the system during the normal and fault condition are studied. In the normal condition, the GSVSC are operated by controlling constant frequency, voltage and phases. During the fault condition, the GSVSC converted to limit current model and dc voltage link are controlled by DFIG-RSC converter. These control strategies are validated in good performance in PSCAD/EMTDC platform.
