Abstract
In the present paper the proposed topology is to improve the power quality of high voltage dc (HVDC) link current which is used for series interconnected offshore wind turbines. The series connection of wind turbines is used with dc-dc converters to build HVDC link voltage. In the present work each wind turbine is furnished with a 5 MW permanent magnet synchronous generator (PMSG) connected to ac-dc-dc converter. 150 MW wind farm is modelled and simulated using thirty units of wind generator with a rated dc link voltage of 125 kV at 1.22 kA. It is observed that the proposed topology reduces the output current fluctuation in HVDC link. The simulation has been done in MATLAB/SIMULINK environment).
