“…Another possible fault type is an open phase, which can be caused by a break in a conductor [IEE01]. It is also possible for one type of fault to develop into another type over time [MK01]. For example, a single-phase to earth fault may evolve into a phase-earth-phase fault [Lou10].…”

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.

Abstract-The acceleration of the speed of the quay crane for containers has raised a higher demand to the dynamic simulation system which is the key part of the simulator in the coast container crane. So it is very necessary to do this research on it. This essay, aimed at the seat motion system of training simulator in the coast container crane, lays a study on the key points in the design of the proprioceptive simulation algorithm of the bridge crane simulator and proposes the realization method for it. This method can help to find the most proper washout point and optimizes the fixed parameter so as to be able to improve the simulation fidelity by offering a better system. It also establishes the simulation model by MATLAB on the basis of which it operates the simulation calculation and analysis on a group of practical motion data. The result shows that this algorithm provides an effective way for the application of the TDOF simulator.

“…S UPERCONDUCTING fault current limiters (SFCLs) offer a variety of benefits for existing and future electrical distribution systems. These include sub-cycle operation in response to faults [1], [2], reduced damage at the point of fault [3], [4], and the opportunity for increased network interconnection [5]. Fault current limiting devices are becoming increasingly important because of the connection of distributed generation (DG) [6] and in systems where fault levels are inherently high, such as marine vessels [3], [7].…”

Superconducting fault current limiters (SFCLs) offer several benefits for electrical distribution systems, especially with increasing distributed generation and the requirements for better network reliability and efficiency. This paper examines the use of multiple SFCLs in a protection scheme to locate faulted circuits, using an approach which is radically different from typical proposed applications of fault current limitation, and also which does not require communications. The technique, referred to as "current division discrimination" (CDD), is based upon the intrinsic inverse current-time characteristics of resistive SFCLs, which ensures that only the SFCLs closest to a fault operate. CDD is especially suited to meshed networks and particularly when the network topology may change over time. Meshed networks are expensive and complex to protect using conventional methods. Simulation results with multiple SFCLs, using a thermalelectric superconductor model, confirm that CDD operates as expected. Nevertheless, CDD has limitations, which are examined in this paper. The SFCLs must be appropriately rated for the maximum system fault level, although some variation in actual fault level can be tolerated. For correct coordination between SFCLs, each bus must have at least three circuits that can supply fault current, and the SFCLs should have identical current-time characteristics.
