Fault ride-through capability for grid-supporting inverters
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016Voltage control strategy has been observed as being more advantageous than current control strategy for microgrid applications where grid-connected and standalone operation of grid-supporting inverters are desired. Voltage control, however, limits the ability to directly control the inverter current.

A Megawatt Converter with Ride-Through Fault Capability
IEEE Transactions on Industry Applications, 1975Protecting thyristors by means of fuses in electro-chemical rectifiers where more than 100 devices are used in a single unit may cause considerable service interruption when fuses open during temporary faults. This paper considers the thyristor and fuse ratings in conjunction with gate suppression techniques to achieve a protective system which allows ...

Transient Modeling and Control of DFIG with Fault Ride Through Capability
2018 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia), 2018The scarcity in the electrical power generation and huge demand of power promotes more renewable energy integration to the grid. This paper proposes a solution for Fault/Low Voltage Ride through (LVRT) problem with dynamic crowbar operation for grid connected Doubly Fed Induction Generator (DFIG) based Wind Energy Conversion Systems (WECS).

Grid Fault Ride-Through capabilities of diesel-electric systems
The XIX International Conference on Electrical Machines - ICEM 2010, 2010The progressive modifications in energy production led to a different grid management. In particular, new standards relative to the grid sustenance during the faults are required. In this paper, a model for the analysis of dynamic behaviour of a diesel-electric genset is proposed.

Doubly fed induction generator wind farm fault ride-through capability
2012 International Conference on Multimedia Computing and Systems, 2012Wind farms WF connected to the power network are frequently subjected to grid faults, a large rotor current rising proportion happens during grid voltage sags. These faults may cause damages to rotor windings, converters, DC Link capacitor or induce drive train mechanical stress due to torque fluctuations.

Capability of asymmetrical grid faults ride-through for DFIG-based Wind turbines
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012In order to meet the grid codes and ensure safe operation of doubly-fed induction generator (DFIG) based wind energy conversion system (WECS) during asymmetrical grid faults, firstly, this paper designs low voltage ride-through (LVRT) control schemes for the back-to-back converters of DFIG-based WECS. Then, due to the converter capacity constraint, the

Enhanced fault ride through capability of matrix converter for wind power system
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013The matrix converter has many advantages in wind power system applications. Matrix converter is compact and highly efficient because it directly converts power from AC generator to the grid without intermediate DC bus while conventional back-to-back converter system requires a lot of electrolytic capacitors in DC link bus which are bulky and have short

Fault ride-through capability of induction generator as offshore wind farm
2016 International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT), 2016As the wind power penetration continues to increase in the modern day electrification, the stabilized operation of wind farms interconnected with grids pose an alarming situation. Typically for an asymmetric grid fault, whose probability of occurrence is more than 70%, the voltage and VAR profile of the wind farm gets disturbed thus leading to ...
