Fault Ride-Through Study of Wind Turbines
Journal of Power and Energy Engineering, 2013 The installation of wind energy has increased rapidly around the world. The grid codes about the wind energy require wind turbine (WT) has the ability of fault (or low voltage) ride-through (FRT). To study the FRT operation of the wind farms, three methods were discussed.

Fault Ride-Through Characteristics of Small Wind Turbines [PDF]
Energies, 2019 There is significant potential for an increase in the use of kilowatt-class small wind turbines (SWTs) in Japan due to reduced limitations with respect to installation, despite their high cost. At this stage, the Japanese grid code has not been considered sufficiently with respect to grid-connected SWTs, and the addition of fault ride-through (FRT ...

Chopperless Fault Ride-Through Control for DC Microgrids [PDF]
IEEE Transactions on Smart Grid, 2021 The dc microgrid should remain connected to the ac utility grid to support the grid stability during faults. However, the bidirectional power flow between the utility grid and the dc microgrid will cause either high-voltage or low-voltage faults at the dc bus.

Photovoltaic inverters with fault ride-through Capability [PDF]
2009 IEEE International Symposium on Industrial Electronics, 2009 This paper presents a new control strategy that allow the photovoltaic system operate under grid faults without overpass the rated current and assuring sinusoidal currents. In the classic control strategies used in photovoltaic systems the power delivered to the grid remains constant when a fault occurs, hence the current can reach dangerous values ...
