Sufficient fault-ride-through (FRT) of large wind power plants (WPPs) is essential for ensuring transmission-grid operational security. The majority of FRT studies do not include all disturbances originated in the transmission grid or include disturbances not relevant for operational security. Using knowledge of power quality, this paper provides a guide to stakeholders in different aspects of FRT for wind turbines (WTs) and wind power plants. This work details the characteristics of the most common disturbances originated in the transmission grid, how they propagate to the wind turbines terminals, and how they impact the dynamic behavior of a large WPP. This work shows that the details of the voltage disturbances at the WT terminals should be considered and not just the voltage disturbance in the transmission grid. Moreover, detailed representation or characterization of voltage dips is important in FRT studies. The simplified models used in the literature are insufficient. This paper strongly recommends that distinct events and additional characteristics as the phase-angle jump and oscillations in the transition segments are considered in FRT analysis.
