“…When the current begins to decay, I5 is smaller than that without CLP. As can be seen from (7) and (8), the reduction of I5 reduces the interruption time and energy dissipation of SA. Additionally, the ETP forms a loop with the inductors which results in the reduction of the interruption time and dissipated energy.…”

Recently the hybrid multi-port DC circuit breaker (MP-DCCB) is becoming popular in protecting HVDC grids, thanks to their reduction of power electronics devices. In this paper, an enhanced multi-port current-limiting DCCB (MP-CLCB) for multiple line protection is proposed. The integrated fault current limiter (FCL) inside the MP-CLCB can clear the fault faster with slightly increased costs. To reduce the energy dissipation requirement for the surge arresters caused by the newly added current-limiting path, an energy transfer path which provides a loop with the inductors during the current decay stage is designed. The theoretical analysis of the precharging, current-limiting, fault interruption and energy dissipation of the MP-CLCB is carried out. Moreover, the design principles of the energy dissipation and the key parameters of the MP-CLCB are provided. The proposed approaches are verified through simulations in PSCAD/EMTDC. The results show that the MP-CLCB can replace multiple DCCBs, accelerate the fault current interruption and reduce the energy dissipation requirement for the surge arresters.

“…Compared to the DC fault ride-through scheme using MMCs with self-blocking sub-modules (SMs), the DC circuit breaker (DCCB) based protection can ensure the selectivity of clearing the DC fault and a fast system restoration [5]- [7]. Hence, DCCBs may have a broad prospect in HVDC grids.…”

“…In [162], the Yttrium Barium Copper Oxygen-coated conductor tape as a resistive type of superconducting fault current limiter is determined as a good candidate for HVDC grid applications. In [163], a study on the parameter matching between active saturated Iron-core superconducting fault current limiter and DC CBs is conducted. In addition, the characteristics of DC CB using transformer-type superconducting fault current limiter for DC fault current interruption are analyzed in [164].…”

High Voltage Direct Current (HVDC) systems are now well-integrated into AC systems in many jurisdictions. The integration of Renewable Energy Sources (RESs) is a major focus and the role of HVDC systems is expanding. However, the protection of HVDC systems against DC faults is a challenging issue that can have negative impacts on the reliable and safe operation of power systems. Practical solutions to protect HVDC grids against DC faults without a widespread power outage include (1) using DC Circuit Breakers (CBs) to isolate the faulty DC-link, (2) using a proper converter topology to interrupt the DC fault current, and/or (3) using high power DC transformers and DC hubs at strategic points within DC grids. The application of HVDC CBs is identified as the best approach that satisfies both DC grids and connected AC grids' requirements. This paper reports a comprehensive review of HVDC CBs technologies, including recent significant attempts in the development of modern HVDC CBs. The functional analysis of each technology is presented. Additionally, different technologies based on information obtained from literature are compared. Finally, recommendations for the improvement of CBs are presented.

“…These modifications were dedicated to decreasing the over-voltage issue on the SC coil and protecting the dc source when a fault occurs. In addition, the parameters matching and constrains between the FCL and direct current circuit breaker (DCCB) were also carried out in [70], [71]. Both theoretical and simulated results show that the k of the FCL is over 1000 since the initial inductance is almost zero, while the react time t c is less than 1ms.…”

Fast emerging fault current levels in high voltage direct current (HVDC) systems has always been a significant obstacle to building a safer and more reliable grid. Inductive fault current limiters (FCLs), compared with its resistive counterpart, are very effective in restricting the fault rising speed that causes major damage during the whole fault process. In this study, a comprehensive review of the methods used for building inductive type FCLs in HVDC systems is presented. The fault current characteristics of the modern HVDC system is discussed to obtain the basic requirements for the FCL. On the basis of different technological domains, various inductive-type FCL topologies and devices are well categorized and analyzed. After the overall discussion and comparison, representative works, as well as new progress and future prospects, are conveyed in detail. One may find the content of this study helpful as a detailed literature review or a practical technical guidance of this field.
