Adaptive CFPREV Control for Cascading Commutation Failure Mitigation Considering Reactive Power Interaction

open access: yesIEEE Access
Advancing the firing angle implemented by the commutation failure prevention (CFPREV) is an effective method for commutation failure (CF), but the increase of reactive power consumption of local inverter would cause adverse influence on voltage at the ac

Research on Battery Energy Storage STATCOM Suppressing HVDC Commutation Failure

open access: yesFrontiers in Energy Research, 2022
Due to the poor performance of traditional STATCOM in DC engineering, a compensation method using battery energy storage STATCOM (STATCOM/BESS) to suppress commutation failure of the weak receiving-end high voltage direct current transmission system is ...

Fear conditioning- and extinction-induced neuronal plasticity in the mouse amygdala [PDF]

open access: yes, 2009
Experience-dependent changes in behavior are mediated by long-term functional modifications in brain circuits. To study the underlying mechanisms, our lab is using classical auditory fear conditioning, a simple and robust form of associative learning. In

A Commutation Failure Prediction and Mitigation Method

open access: yesJournal of Modern Power Systems and Clean Energy, 2022
The mitigation of commutation failure (CF) depends on the accuracy of CF prediction. In terms of the large error of the existing extinction angle (EA) calculation during the fault transient period, a method for CF prediction and mitigation is proposed ...

Extinction of cue-evoked drug-seeking relies on degrading hierarchical instrumental expectancies [PDF]

open access: yes, 2014
There has long been need for a behavioural intervention that attenuates cue-evoked drug-seeking, but the optimal method remains obscure. To address this, we report three approaches to extinguish cue-evoked drug-seeking measured in a Pavlovian to ...

Suppression to concurrent commutation failure of UHVDC with hierarchical connection mode based on improved dc current prediction

open access: yesIET Generation, Transmission & Distribution, 2023
For the ultra high‐voltage dc (UHVDC) transmission with hierarchical connection mode (HCM) at the inverter side, local commutation failure (LCF) at one layer after the ac fault may cause concurrent commutation failure (CCF) at the non‐fault layer.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
