Dynamic Performance Analysis and Fault Ride-Through Enhancement by a Modified Fault Current Protection Scheme of a Grid-Connected Doubly Fed Induction Generator

open access: yesMachines
With the increase in reliance on doubly fed induction generator-based wind energy conversion systems (DFIG-WECSs), extracting maximum power from wind energy and enhancing fault ride-through (FRT) techniques meeting the grid code requirements is the ...

Distributed Energy Resource Behavior During Faults: Navigating Voltage Ride‐Through Compliance Within the Realm of EN 50549

open access: yesIET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
This study examines how increasing inverter‐based RERs affect fault propagation in MV DNs, ensuring adherence to European grid codes EN 50549‐1 and EN 50549‐2 concerning LVRT requirements. A model predictive current control strategy, an LVRT, and secondary power controllers are developed and tested using a detailed MATLAB/Simulink model of the Sundom ...

Transient characteristics and adaptive fault ride through control strategy of DFIGs considering voltage phase angle jump

open access: yesJournal of Modern Power Systems and Clean Energy, 2017
Wind power in China has experienced fast development in recent years. However, areas rich in wind power resources are often far away from loads centers, which leads to weak connection between wind turbines and power grid.

Enhancement Fault Ride-Through Capability of DFIG By Using Resistive and Inductive SFCLs [PDF]

open access: yes, 2014
The number of wind turbines connected to the grid is steadily increasing in recent years. This situation forced the revision of the electric utilities grid codes requirements, to remain connected during grid faults, i.e., to ride through the faults ...

A Novel Hybrid Statistical Method for Power Swing Detection in Transmission Lines With Grid‐Following Inverter

open access: yesIET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
This paper develops a novel statistical framework, integrating a cumulative sum control chart and entropy analysis, for power swing and fault discrimination, which enables accurate detection and differentiation of faults and power swings in grid‐following‐connected transmission lines.

Optimizing Fault Ride-Through of DGs in Distribution Networks to Preserve Recloser-Fuse Coordination

open access: yesIEEE Access
Fuse saving protection is usually applied in distribution networks, through auto-reclosing, to prevent fuse burning under transient faults. The modern fault ride-through (FRT) standards, which require distributed generators (DGs) to remain connected ...

Fault Ride-through Capability Enhancement of Voltage Source Converter-High Voltage Direct Current Systems with Bridge Type Fault Current Limiters

open access: yesEnergies, 2017
This paper proposes the use of bridge type fault current limiters (BFCLs) as a potential solution to reduce the impact of fault disturbance on voltage source converter-based high voltage DC (VSC-HVDC) systems.

Enabling Temporary Blocking of Offshore Converters Through Grid‐Forming Wind Turbines to Assist HVDC Grid Protection

open access: yesIET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
The paper higlights the usage of GFM WTG to enable temporary blocking of the offshore converter in MT‐HVDC systems to reduce protection requirements. It is shown, that smaller DCCB series inductances can be used. During temporary blocking the AC power transfer is interupted but is returned quickly after the converter is brought back into operation ...

Improving fault ride‐through capability for doubly‐fed induction generator based on improved system structure and corresponding control scheme

open access: yesIET Energy Systems Integration
Although there are many methods to improve the fault ride‐through (FRT) capability of doubly‐fed induction generator (DFIG) systems at present, each method has its shortcomings, especially the applicability under different voltage dips (VDs), so an ...
