Fault Characteristic Analysis and a Novel Pilot Protection Scheme for Pole-to-Ground Fault in Flexible DC Distribution Network

open access: yesIEEE Access, 2023
Due to the pseudo-bipolar structure of the flexible DC distribution network, the short-circuit current caused by a pole-to-ground fault is weak. The fault characteristics, particularly the steady-state fault characteristics, are not prominent. Therefore,

Pilot protection schemes over a multi-service WiMAX network in the smart grid [PDF]

open access: yes, 2013
Pilot protection schemes, extensively used in high voltage transmission grids, are one of the most effective methods of protecting networked distribution lines that use high speed inter-relay communications for fast fault detection and isolation.

Mechanically-assisted crevice corrosion and its effect on materials degradation

open access: yesCorrosion Communications, 2023
Mechanically-assisted crevice corrosion (MACC) is a synergistic combination of wear and crevice corrosion. The major differences between tribocorrosion, fretting corrosion and MACC relate to the relative scale of motion and contact area, are clarified in

Microstructure Refinement on Crevice Corrosion of High-Speed Rail Steel U75V Visualized by an In Situ Monitoring System

open access: yesFrontiers in Materials, 2022
Rail foot covered by a fastener will suffer from crevice corrosion, leading to thinning and localized attack of crevice interior posing a risk of failure. This work investigated crevice corrosion behavior of a typical pearlitic high-speed rail steel U75V,

The Pilling-Bedworth Ratio of Oxides Formed From the Precipitated Phases in Magnesium Alloys

open access: yesFrontiers in Materials, 2021
The Pilling-Bedworth ratio of oxides preferentially formed from the precipitated phases in magnesium alloys were calculated. The results showed that the PBR value of Nd2O3 preferentially formed from Mg12Nd was 1.0584, and the PBR value of Y2O3 ...
