Fault Ride-Through Optimization Scheme for Hybrid AC/DC Transmission Systems on the Same Tower [PDF]

open access: yesSensors
Sensors in power systems utilize the detection results of fault signals to guide subsequent fault handling procedures. However, the traditional phase-shift restart strategy exhibits limitations such as power interruptions, reactive power redundancy, and ...

Protection of transmission lines using fault component integrated power

open access: yesIET Generation, Transmission and Distribution, 2014
In this study, a novel scheme is proposed for pilot protection of transmission line based on the fault component integrated power (FCIP). An appropriate definition is proposed for FCIP. The proposed scheme is able to quickly discriminate the normal condition, internal fault and external fault situations, even in severe operating and emergency ...

Audible noise spectral characteristics of high‐voltage ac bundled conductors at high altitude

open access: yesIET Generation, Transmission & Distribution, 2021
At high altitudes, the corona discharge around a conductor surface is severe, and the induced audible noise (AN) is irritating; this is due to the low air density at high altitudes.

A hybrid network IDS for protective digital relays in the power transmission grid [PDF]

open access: yes2014 IEEE International Conference on Smart Grid Communications (SmartGridComm), 2014
In this paper, we propose a novel use of network intrusion detection systems (NIDSs) tailored to detect attacks against networks that support hybrid controllers that implement power grid protection schemes. In our approach, we implement specification-based intrusion detection signatures based on the execution of the hybrid automata that specify the ...

Simulation of Influence of DC Pre-Stress on Space-Charge Characteristics of Cross-Linked Polyethylene in Inhomogeneous Field

open access: yesIEEE Access, 2020
Space charge is one of the main causes of electrical tree initiation in high-voltage cable insulation. To investigate the influence of DC pre-stress on the space-charge distribution of cross-linked polyethylene (XLPE), a two-dimensional needle-plate ...

Under-voltage Protection of Power Transmission Lines

open access: yesJournal of Energy Research and Reviews, 2023
The continuous monitoring of the protection relay of the transmission line is desirable to ensure the system disturbance such as fault inception is detected in the transmission line. Therefore, the fault on the transmission line needs to be detected, classified, and located accurately to maintain the stability of the system.
