“…This huge power loss occurs during the on-state conduction because the resistance of the new solid state DC breakers is negligibly small. Though the cost of the new solid state breakers seems prohibitive, in reality it is not so, because the fast switching of the IGBT provides excellent protection against the internal converter faults and short-circuit on the DC transmission network whose cost are relatively high.Further comparisons of the DC breakers based on various voltages are shown in [5]. From table 1 and 2, we find that the solid-state CB are cheaper compared to other four types of DC breakers and have the ability for fast switching operation.…”

“…In a multi-terminal system with large wind power integration, a fault on one converter can be cascaded to other converter stations; consequently a fast DC breaker is necessary to protect the VSC-HVDC system. To avert the damage it is important to use an HVDC circuit breaker that can quickly isolate the faulty section from the system [5]. VSC-HVDC system utilizes Insulated Gate Bipolar Transistors (IGBT) for fast switching purposes.…”

“…In order to maintain the reliability of supply system, the fault should be cleared within a few milliseconds. In this regard, numerous HVDC circuit breaker (CB) designs have been reported in the literature [21], [22]- [25]. The HVDC CBs are classified into two categories namely, solid state CB and the hybrid CB.…”

Abstract-The subsea industry has become more predominant in recent years because of the discovery of a significant number of new oil and gas fields located in deep water, a term often used to describe offshore projects located in water depths greater than 600 feet. In order to extract oil and gas, a large number of electrical systems need to be deployed at the seabed. Many of these electrical systems need high-reliability power grid and power control units located on the seabed to minimize downtime. Power system and power electronics play a major role in providing the required and reliable power to various electrical systems. But there are many challenges for deploying power components under the seabed. This paper presents the challenges and the requirements of power system components operating in subsea environment, use of power electronics for efficient transmission of power from the offshore platform or from the shore to the subsea electrical loads; variable speed drive systems; and research areas related to power electronics for subsea electrical systems.

“…Using HVDC circuit breakers to interrupt and isolate a DC fault has been discussed in literature, such as in [6][7][8][9][10] and industrial DC circuit breaker prototypes are being produced [7,11,12]. A Fault Current Limiter (FCL) may be used to limit the fault current the DC circuit breaker needs to interrupt.…”

Multi-terminal Voltage-Sourced Converter (VSC) High Voltage Direct Current (HVDC) transmission is expected to play a key role in future power transmission grids. Compared with AC transmission, DC transmission is more vulnerable to faults due to the lower DC side impedances and sensitive power electronics used in the converters. DC protection issues must be solved before any multi-terminal VSC-HVDC grid can be established. In terms of DC protection, apart from using a DC circuit breaker to interrupt and isolate a DC fault, a Fault Current Limiter (FCL) may be employed to limit the fault current. FCLs could potentially form an important part of any future DC protection system. This paper investigates such a FCL. The main contribution of this paper is that, the resistive type superconducting FCL (SCFCL) is modelled in detail to perform DC protection with the ABB hybrid circuit breaker, in a high fidelity four-terminal VSC-HVDC system model. The simulation results show that the SCFCL has great potential to be employed for DC protection.
