“…After opening a circuit breaker to clear a fault, the circuit breaker is held open for a period of time, known as the dead time. The dead time allows for de-ionisation of the air gap at the fault location (or, if single-pole autoreclose is used, the dead time must also allow for the secondary arc to extinguish [Web95]). Following the dead time, the circuit breaker is reclosed to attempt to restore the supply of power.…”

Fault current levels in electrical systems are rising due to natural growth in demand, the increasing presence of distributed generation (DG), and increased network interconnection. This rising trend is expected to continue in the future.Marine vessel power systems are highly power-dense and are often safety-critical.Power system protection is increasingly challenging in these systems. Superconducting fault current limiters (SFCLs) offer an attractive solution to many of the issues faced.This thesis establishes and reviews the state of the art in resistive SFCL technology and application knowledge, and provides crucial research-based guidance for the adoption of resistive SFCLs in future power systems.The issues associated with the application of resistive SFCLs-including location, resistance rating, the recovery period, and interaction with protection systems-are demonstrated. The relationship between several resistive SFCL design parameters is established using a generic analytical approach, hence providing a framework for validating SFCL designs. In particular, it is shown that a particular SFCL resistance rating leads to a peak in the superconductor energy dissipation, which generally should be avoided.It is proven that resistive SFCLs have an inverse current-time characteristic, i.e., they will operate in a time that inversely depends upon the initial fault current magnitude. This knowledge is critical for underpinning the operation of a novel protection scheme using multiple resistive SFCLs. The scheme offers several advantages: very fast-acting operation in response to faults anywhere on the system under study; maximum prospective fault currents are prevented from occurring, reducing the duty on circuit breakers; inherent, fast-acting backup; and communications is not required. It is shown that the scheme is suited to highly-interconnected systems with a high presence of DG. The scheme is readily applicable to the design of future utility and marine vessel power systems.

“…The prevailing suppressing technologies for secondary arcs extinction include installation of four‐legged inductors, fast grounding switches, series compensation, hybrid trigged trip as well as transmission line partitions , based on which many further ameliorated measures have been put forward. For an example, with regard to dual parallel lines on the same tower, different configuration of shunt inductors may be adopted to compensate the coupling effect between the healthy line and the faulty line, with a view to realizing reliable extinction of the secondary arcs and reactive power balance of the power systems .…”

SUMMARY A novel scheme is proposed for secondary arc extinction, preferably applicable to extra high voltage (EHV) and ultra high voltage (UHV) transmission lines. The topology and the operational principle of the scheme are elucidated in details. Mathematical expressions for topology parameters design and optimization under different conditions have been established based on equivalent circuit transform and are verified by simulations. Results suggest that the proposed methodology can largely reduce the forced component of the secondary arc current, one part of the complete response of a circuit under excitation. The recovery voltage is not affected by fault location, transmission power and the shunt inductors. The decay factor and oscillation frequency of the free components of the secondary arc current and the recovery voltage are also computed based on the equivalent impedance network and Laplace Transform. In addition to causing possible resonant overvoltage, the proposed theme may prolong the arcing time due to cancelling zero‐crossing of the secondary arc current while shunt inductors are installed at the transmission line terminals. Simplified formula for calculating the critical compensation point are given as to be used as a reference for the re‐optimization of the novel theme. The proposed methodology presents an alternative to suppress the secondary arcs for EHV and UHV transmission lines. Copyright © 2013 John Wiley & Sons, Ltd.

“…SPAR provides an improvement in the overall operational service quality of the system. During the single phase faults, approximately 50% of the transmission capacity may still be retained via two sound phases when faulted phase is opened [2]. Despite of the many advantages, possibility of reclosing onto permanent faults, due to fixed or non adaptive time intervals, is the main disadvantage of the traditional SPAR systems.…”
