In This Paper Wind Systems, A/S which is one of the leading manufacturers of wind turbine systems in the world. The proposal deals with DC-DC connected offshore wind system. This is a promising technical solution regarding the increasing demand of electrical power and the long distances between on- and offshore sites. The main goal is the development of steady state models of an entire wind turbine system with selected AC-DC converters between the generator output and DC-DC connection of the wind turbines. The Buck-boost with a high frequency transformer and a three phase rectifier are selected for modeling this thesis. The models are used as a basis for the simulations of the two different wind turbine systems with a wind speed ramp as input. Relying on these simulations two performance factors are investigated, torque and speed, relating to which performance of DC drive is analyzed.
