The study of a hypothetical large offshore wind farm based on centralised power conversion and interconnected to the grid using multiterminal parallel high voltage direct current (HVDC) link is presented. 300 MW consists 60 squirrel-cage 5 generators connected common DC bus ten source converters (VSCs). transmission system provide variable speed generator control, therefore individual are not required for each generator, implying savings in costs. paper studies technical economical benefits proposed topology, as well selection main components. A detailed analysis control circuits both facing converters, with respect primary functions, also given. PSCAD/EMTDC simulation concept presented realistic signals. results confirm operation at an average optimum coefficient performance respective group, satisfactory stability even severe changes. reduces costs associated interconnection may simplify integration farms substantial distances.
