Synchronous Recovery of Waveforms From Dynamic Phasors Models of LCC-HVDC Links

IEEE Access
LCC-HVDC links are used worldwide for long-distance bulk power transmission in large scale power systems. In this technology, commutation failure phenomena may occur, where transient power interruptions of HVDC links may lead the system to ...

When property becomes rent

American Ethnologist, EarlyView.
Abstract For millions of working‐class Mexicans, property has turned into rent. This transformation has fundamentally dislocated social reproduction in Mexico by eroding households’ ability to envision themselves as holders of patrimony and as lasting social formations. To understand how and to what effect property turned into rent, we must look to the

Heads Up: A Retrospective Review of Paediatric Trauma Secondary to Electric Scooters at a Tertiary Paediatric Trauma Centre in Queensland

ANZ Journal of Surgery, EarlyView.
ABSTRACT Background Since the introduction of electric scooters (e‐scooters), there has been a rise in related injuries and subsequent healthcare burden. There is a paucity of published research regarding paediatric e‐scooter injuries in Australia.

The Covid‐19 Pandemic and Pre‐Existing Migration Infrastructures: Differentiated Impacts on Nepali Migrants in Japan

Asia Pacific Viewpoint, EarlyView.
ABSTRACT The COVID‐19 pandemic disproportionately affected international migrants worldwide. However, not all international migrants were uniformly impacted. While much of the literature has focused on the pandemic's effects on migrants relative to citizens, the impacts faced by different groups of migrants remain less understood.

Subsequent commutation failure suppression strategy of hybrid cascaded HVDC system based on coordinated control of CEC and VDCOL

IET Energy Systems Integration
The inverter side of hybrid cascaded HVDC adopts the structure of Modular Multilevel Converter (MMC) in series with Line Commutated Converter (LCC). The complete system amalgamates the advantages of LCC with MMC, but it also makes the interaction process

Mitigating commutation failures in HVDC systems with SFCL deployment

International Journal of Electrical Power & Energy Systems
Commutation failures represent a prevalent issue encountered in line-commutated-converter high voltage direct current (LCC-HVDC) systems. As the widespread deployment of HVDC systems continues, the risk associated with commutation failures increases ...
