Improved DFIG Capability during Asymmetrical Grid Faults [PDF]
, 2015 In the wind power application, different asymmetrical types of the grid fault can be categorized after the Y/d transformer, and the positive and negative components of a single-phase fault, phase-to-phase fault, and two-phase fault can be summarized. Due

DC fault protection of diode rectifier unit based HVDC system connecting offshore wind farms [PDF]
, 2018 DC fault ride-through operations of the offshore wind farm connecting with diode rectifier unit (DRU) based HVDC link are presented in this paper. A voltage-error-dependent fault current injection is proposed to regulate the WT current during DC faults ...

Addressing Economic Insecurities Can Improve Patient‐Reported Outcomes in Lupus
Arthritis Care &Research, Accepted Article.Background Economic insecurities, such as food, housing, transportation, and financial challenges, are modifiable risk factors and influence patient‐reported outcomes (PROs) in systemic lupus erythematosus (SLE). We examined: 1) associations between economic insecurities and PROs; 2) the impact of screening and addressing economic insecurities during ...

N‐heterocyclic Carbenes as Adhesion Promoters on Aluminum Alloy 6061
Advanced Materials Interfaces, EarlyView.N‐heterocyclic carbenes as novel non‐toxic surface primers for aluminum alloys for better adhesive bonding, because strong adhesive bonding shouldn't come at the cost of poisoning the human body. The impact of NHC functionalization on adhesive joint strength and durability is also evaluated using a single‐lap‐shear test, following continuous exposure ...
