“…However, failure by the breaker to timely isolate the fault can be detrimental to both human being and the components being protected thus, hybrid CB continues to attract a lot of attention as recently witnessed in [19]. Further, ABB and ALSTOM have developed Hybrid HVDC CB prototypes with some considerable improvements in recent research [11], [20]- [21]. There are many available topologies of hybrid CB at various stages of development, but only two attract more attention.…”

“…For medium and high voltage applications, vacuum and sulphur hexafluoride (SF 6 ) have already replaced the previous air and oil solutions and have become the most widely used types of circuit breaker. In this paper, the mechanical switches refer to either vacuum interrupters or SF 6 circuit This paper is a postprint of a paper submitted to and accepted for publication by, and is subject to Institution of Engineering and Technology Copyright.…”

“…The rise rate of short circuit currents in DC networks is also much higher due to the lower system impedances. Hybrid HVDC circuit breakers comprised of mechanical switches, semiconductors and varistors have been investigated by several manufactures [5,6]. The conduction losses of the solid-state semiconductors however still dominate the DC circuit breaker losses.…”

High voltage direct current (HVDC) circuit breakers are a key technology to enable fault management for multi terminal DC (MTDC) networks. DC circuit breakers using superconductors for current limiting have been proposed previously and experimentally tested at low voltage levels. Superconductor materials are ideal for DC networks: they do not incur losses operating with pure DC current. This paper will focus on the interface between the superconductor element and the other elements of the breaker, i.e., the mechanical switch and semiconductor elements. A 10 kV DC circuit breaker will be developed based on the optimized interface and control strategy.

“…Although HVDC circuit breakers are not commercially available yet, the development of several HVDC circuit breaker prototypes indicates that interrupting DC currents in the order of kA can be CrossCheck date: 20 June 2016 achieved in just few milliseconds [3][4][5]. In the literature, most research on DC protection has focused on developing fast and selective DC protection algorithms, which can be categorized into unit protection [6,7] and non-unit protection [8][9][10][11][12].…”

This paper proposes a frequency domain based methodology to analyse the influence of High Voltage Direct Current (HVDC) configurations and system parameters on the travelling wave behaviour during a DC fault. The method allows us to gain deeper understanding of these influencing parameters. In the literature, the majority of DC protection algorithms essentially use the first travelling waves initiated by a DC fault for fault discrimination due to the stringent time constraint in DC grid protection. However, most protection algorithms up to now have been designed based on extensive time domain simulations using one specific test system. Therefore, general applicability or adaptability to different configurations and system changes is not by default ensured, and it is difficult to gain in-depth understanding of the influencing parameters through time domain simulations. In order to analyse the first travelling wave for meshed HVDC grids, voltage and current wave transfer functions with respect to the incident voltage wave are derived adopting Laplace domain based component models. The step responses obtained from the voltage transfer functions are validated by comparison against simulations using a detailed model implemented in PSCAD TM . Then, the influences of system parameters such as the number of parallel branches, HVDC grid configurations and groundings on the first travelling wave are investigated by analysing the voltage and current transfer functions.
