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 ...

Unbalanced-Grid-Fault Ride-Through Control for a Wind Turbine Inverter
IEEE Transactions on Industry Applications, 2007Large variable speed wind turbines with fully rated, direct-in-line converters are increasingly used as silicon cost continues to decline. While grid codes require wind turbines to ride-through grid faults, including unbalanced faults, voltage source inverters interfaced to the grid are inherently sensitive to any unbalance in the a.c. voltage.

Assessment of Fault Ride Through Requirement for Distributed Generators
3rd Renewable Power Generation Conference (RPG 2014), 2014One of the biggest changes the power industry will encounter over the next twenty years will be the significant increase of embedded generation connecting directly to the distribution system. Amongst various generator connection requirements required to ensure network resilience, Fault Ride Through requirement may be one of the key areas which requires

Fault Current Suppression for the Fault Ride-Through of Triple-Active-Bridge Converters
IEEE Transactions on Industrial ElectronicsThe fault ride-through (FRT) capability is an important ancillary service for power converters in dc power distribution systems. Despite extensive research, the triple active bridge converter (TABC) has been perceived as lacking FRT capability due to the requirement of blocking all power switches in the event of a dc short-circuit fault at the dc ...

Fault Ride Through for a DC ring bus microgrid
2016 International Conference on Energy Efficient Technologies for Sustainability (ICEETS), 2016DC microgrid is gaining more prominence due to the development of renewable resources that generate DC output and also due to the increasing use of DC in end-user equipments. Also with DC system, connection of backup energy storage and small size generation is easier to realize. For any system, disconnecting a part of the system during temporary faults

Fault ride-through of doubly-fed induction generators
2012 International Conference on Power, Signals, Controls and Computation, 2012The aim of this paper is to explore the various dynamic controllers to enhance the fault ride-through (FRT) of doubly-fed induction generators (DFIGs). A wind farm of total capacity 9 MW is considered for the study. The flexible AC transmission system (FACTS) controllers like Static Synchronous Compensators (STATCOM) and Unified Power Flow Controllers (

Analysis of SFCL for Improving Fault Ride Through of DFIG
2020 IEEE International Conference on Applied Superconductivity and Electromagnetic Devices (ASEMD), 2020With the wide use of the wind power energy, Doubly Fed Induction Generator (DFIG) plays an important role in the power grid. Because the stator side of DFIG is connected with the grid, the fault ride through (FRT) is widely followed by people. To reduce the cost of the fault current limiter (FCL) economically, adopting a resistive-type superconducting ...

Fault ride-through capability of DFIG wind turbines
Renewable Energy, 2007This paper concentrates on the fault ride-through capability of doubly fed induction generator (DFIG) wind turbines. The main attention in the paper is, therefore, drawn to the control of the DFIG wind turbine and of its power converter and to the ability to protect itself without disconnection during grid faults. The paper provides also an overview on

Investigations into fault ride through and fault location for HVDC
2019Voltage Source Converter - High Voltage Direct Current (VSC-HVDC) transmission systems have been rapidly developed and received great interest in off-shore wind power applications, because of the increase in the energy demand, compact size and ability to connect asynchronous AC systems. Multi-Terminal Direct Current (MTDC) networks have great potential
