Impact of Fault Ride-Through on Wind Turbines Systems Design

Many countries plane to rely on renewable energy sources for their electricity production. Recently, the wind turbine connection under different conditions and dynamic behavior has become an important issue in grid codes. The capability of fault ride-through of wind turbines is the high important requirement related to national grid codes. Based on that, wind turbine should stay connected to the network during various scenarios of fault grid to maintain the system stability. Moreover, the generator of wind turbine should be designed to have the capability to provide reactive power during the faults. Immediately after fault clearance, generators have to supply active and reactive power to support grid voltage and frequency, respectively. In this paper, an exhaustive review of researches published about effective of Fault Ride-Through (FRT) of wind turbines with different generator systems is presented. In this review, the authors concludes that many investigations and researches should be focused to fulfill the parameter of wind turbine design. In particular, the real and reactive power needs of grid codes should be taken into account in more profundity in the future FRT solutions. Furthermore, solutions based on machine design and power electronics has been detailed.
