Protection strategy for multi-terminal DC networks with fault current blocking capability of converters [PDF]

, 2017
High voltage dc networks are a promising technology to flexibly transmit power over long distances. However, dc grid protection is still a major challenge. DC fault clearance can be mainly achieved with three devices. These are ac circuit breakers (ACCBs)

Adaptive Single-Phase Auto-Reclosing Approach for Shunt Compensated Transmission Lines

IEEE Transactions on Power Delivery, 2021
Single-phase auto-reclosing (AR) scheme is widely employed in extra high voltage (EHV) transmission networks to quench transient faults without completely removing the faulted transmission line (TL). Long EHV TLs are commonly equipped with shunt reactors to reduce the Ferranti effect overvoltages.

Lyapunov Functions Family Approach to Transient Stability Assessment [PDF]

, 2015
Analysis of transient stability of strongly nonlinear post-fault dynamics is one of the most computationally challenging parts of Dynamic Security Assessment. This paper proposes a novel approach for assessment of transient stability of the system.

An Adaptive Reclosing Scheme for Cross-Line Faults on Double-Circuit Wind Power Outgoing Lines with Shunt Reactors

Energies
Wind turbines are vulnerable to negative sequence current injection, the conventional automatic reclosing scheme for wind power outgoing lines, since we may inject negative sequence components into the system and reclose it without distinguishing the ...

Understanding bidirectional and transactional relations in parent and offspring mental health: Using COVID‐19 pandemic data to gain insights

JCPP Advances, EarlyView.
This study found that parent internalising symptoms predicted internalising symptoms in younger children, with no evidence of child‐driven effects. Among adolescents, mental health symptoms showed bidirectional associations with parent internalising symptoms, particularly for externalising symptoms.

Adaptive Autoreclosing Scheme for Line-to-Line Nongrounded Faults on Double-Circuit Transmission Lines Based on Phase-to-Phase Reactive Power

IEEE Access, 2020
Double-circuit transmission lines play a very important role in electric power transmission. When a line-to-line nongrounded fault occurs on double-circuit transmission lines, for traditional tripping and reclosing methods, tripping of all six phases may

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Lead Impacts on the Moist Static Energy Budget of the Low‐Level Arctic Atmosphere in Large‐Eddy Simulations Based on MOSAiC Data

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract High‐resolution large‐eddy simulations (LES) are used to examine the impact of Arctic sea‐ice leads on the wintertime lower atmosphere. Leads expose the cold atmosphere to the relatively warm ocean, and are thus critical to the Arctic energy budget.

Adaptive single-phase auto-reclosing method using power line carrier signals

International Journal of Electrical Power & Energy Systems, 2018
Abstract This paper proposes a new method for adaptive single-phase auto-reclosing (ASPAR) that improves the rate of successful reclosing actions after the occurrence of a transient single-phase fault and prevents unsuccessful reclosing. After the occurrence of a fault, the only faulty phase is disconnected by the protection system (e.g., distance ...
