Abstract

Fulfilling the new grid codes constitutes one of the main challenges for the wind power industry, that is specially concerned about the new fault-ride-through requirements. Enhancing the operation of wind-turbines in front of grid faults is not only an important issue for new wind farms, but also for the existing ones, as, at the present time, the classical squirrel cage induction generatorpsilas wind turbines still represent a 30% of the wind power production. Reinforcing the operation of such facilities can be performed taking advantage of the increasing number of modern power systems that are linked to the grid by means of power processors. In order to analyse the feasibility of this proposal, this paper test different control strategies to be implemented in a modern variable speed wind turbine, equipped with a synchronous generator and linked to the grid through a full power converter, that permits improving the fault-ride-throughcapability of a classical fixed speed wind turbine, based on a squirrel cage induction generator, installed in its neighborhood.
