Externally gapped line arresters placement effect on transmission line lightning performance including the frequency response of the grounding system

IET Generation, Transmission &Distribution, Volume 17, Issue 22, Page 4975-4990, November 2023., 2023
• The externally gapped line arrester (EGLA) performance, which incorporates the frequency grounding system, has been explored as a new approach. • The effect of port length, diameter, and grounding electrode shape on the grounding system impedance has been modelled.

Power-Smoothing Scheme of a DFIG Using the Adaptive Gain Depending on the Rotor Speed and Frequency Deviation [PDF]

, 2017
In an electric power grid that has a high penetration level of wind, the power fluctuation of a large-scale wind power plant (WPP) caused by varying wind speeds deteriorates the system frequency regulation. This paper proposes a power-smoothing scheme of

Modeling a Hybrid Diode-Thyristor HVDC Rectifier in EMTP-RV [PDF]

2006 Canadian Conference on Electrical and Computer Engineering, 2006
This paper presents the investigation into the viability of a hybrid diode-thyristor High Voltage Direct Current (HVDC) rectifier. The large-scale usage of HVDC transmission is limited by several factors and one of the most important factors is the high cost of conversion equipment.

A review of power system resilience assessment and enhancement approaches by focusing on wind farms and wind turbines

IET Renewable Power Generation, Volume 17, Issue 9, Page 2391-2410, 6 July 2023., 2023
Here, assessment and enhancement approaches of power system resilience by focusing on the role of wind farms and wind turbines are reviewed. To do so, a comprehensive review of the related metrics, assessment methods, and enhancement solutions is presented. The existing works have studied the resilience of power system from the perspectives of planning

Research on the arcing horn with active arc extinguishing function for HVDC grounding electrode line

IET Generation, Transmission &Distribution, Volume 17, Issue 11, Page 2634-2643, June 2023., 2023
In this work, an active arc extinguishing method based on variable resistance for arcing horn was proposed. To design the arcing horn within active arc extinguishing function, the grounding electrode line and arcing horn model were established based on a ±800kV UHVDC transmission system. The electrical characteristics of the arcing horn were calculated

Residual charge effects on partial discharges' response to varying sub‐kHz voltage frequencies

High Voltage, Volume 8, Issue 3, Page 622-629, June 2023., 2023
Abstract Partial discharges (PD) are the ‘cancer’ of electrical insulation. Insulation design and mitigation of PD‐induced degradation should be based on good knowledge of PD phenomena. In that regard, a significant body of knowledge has been built up from concerted research across the world in past decades and on various aspects of PD phenomena under ...
