Technical Assessment of Hybrid HVDC Circuit Breaker Components under M-HVDC Faults

Energies, 2021
One of the technical challenges that needs to be addressed for the future of the multi-terminal high voltage direct current (M-HVDC) grid is DC fault isolation. In this regard, HVDC circuit breakers (DCCBs), particularly hybrid circuit breakers (H-DCCBs),

Coordinated control of DC circuit breakers in multilink HVDC grid

CSEE Journal of Power and Energy Systems, 2021
High voltage DC grid is developing towards more terminals and larger transmission capacity, thus the requirements for DC circuit breakers (DCCB) will rise. The conventional methods only use the faulty line DCCB to withstand the fault stress, while this paper presents a coordination method of multiple DCCBs to protect the system.

Analysis of Out‐of‐Step Oscillation Centre Migration Under Increasing Renewable Energy Penetration in Large‐Scale Power Systems

IET Smart Energy Systems, Volume 2, Issue 3, Page 181-190, September 2026.
Increasing renewable penetration causes out‐of‐step oscillation centres to migrate away from renewable integration points. Two distinct migration modes—continuous drift and large‐range jumps with instability‐mode changes—are identified, providing guidance for adaptive splitting protection in future power systems.

Type Tests for Hybrid HVDC Breakers: a Technical Feasible Solution

, 2023
In the coming years, the use of the HVDC circuit breakers will become a necessity in the “grids of the future” (basically multi-terminal HVDC grids). An obliged step is to test such equipment before to install it on the grids.

A Novel Topology of Hybrid HVDC Circuit Breaker for VSC-HVDC Application [PDF]

Energies, 2017
The use of high voltage direct current (HVDC) circuit breakers (CBs) with the capabilities of bidirectional fault interruption, reclosing, and rebreaking can improve the reliable and safe operation of HVDC grids. Although several topologies of CBs have been proposed to perform these capabilities, the limitation of these topologies is either high on ...

Dynamic Behaviour of Bubbles in Oil Under Electrothermal Ageing

High Voltage, Volume 11, Issue 4, Page 975-986, August 2026.
ABSTRACT During long‐term operation of converter transformers, the internal oil–pressboard insulation undergoes irreversible degradation. Partial discharge in the weakened insulation will cause the formation of a large number of bubbles in the insulating oil.
