Abstract

This paper proposes a novel fault-ride through method for offshore wind farms connected to grid through a voltage source converter (VSC)-based high voltage direct current (HVDC) transmission. The proposed method introduces a controlled voltage drop at offshore grid when an onshore fault occurs. The idea behind is to achieve a fast power reduction. Additionally in the proposed idea, every individual wind turbine detects the voltage drop of offshore grid almost simultaneously, then its controller decreases the power set-point to reduce the power output from each wind turbine. The effectiveness of this method is verified by numerical simulations performed in PSCAD.
