Continuous Operation of Wind Power Plants under DC Line Faults in Multi-Circuit HVDC Transmission System

open access: yes, 2021
This paper focuses on the multi-circuit HVDC transmission system which can localize DC line faults. The conventional method requires to shutdown and restart the wind power plants after the DC line faults, resulting in the long-term suspension of the ...

Research on Adaptive Power Transmission Line Fault Inspection

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract Power transmission line is one of the most important infrastructures of power system, and its safety monitoring is of great significance. The conventional way of fault monitoring of power transmission lines by only setting threshold value on single temperature data of strain clamp turned out to multiple misjudgements and delayed

A Review of Fault Diagnosing Methods in Power Transmission Systems [PDF]

open access: yesApplied Sciences, 2020
Transient stability is important in power systems. Disturbances like faults need to be segregated to restore transient stability. A comprehensive review of fault diagnosing methods in the power transmission system is presented in this paper. Typically, voltage and current samples are deployed for analysis.

Detection and Classification of Transmission Line Faults Using Stockwell Transform and Rule Based Decision Tree

open access: yes, 2018
This paper presents an algorithm for detection and classification of different types of the power system faults occurring on the transmission line to provide the effective protection to the line against these faults. The proposed technique uses Stockwell

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Living and Working Safely Around High-Voltage Power Lines. [PDF]

open access: yes, 1998
High-voltage transmission lines can be just as safe as the electrical wiring in the homes--or just as dangerous. The crucial factor is ourselves: they must learn to behave safely around them.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
