Analysis of the fault current limiting requirement and design of the bridge‐type FCL in the multi‐terminal DC grid

IET Power Electronics, 2018
In the multi‐terminal flexible dc grid, it is important for the healthy network to ride through the dc fault. The converters should operate continuously after dc faults, staying unblocked. But the existing selective protection and isolation method may fail to react swiftly enough, because the propagation speed of the dc fault current is extremely fast.

Redefining Optimal Coverage Path Planning for FLS‐Equipped AUVs With Deep Reinforcement Learning

Journal of Field Robotics, EarlyView.
ABSTRACT Autonomous Underwater Vehicles (AUVs) have emerged as indispensable tools for a variety of subsea tasks, from habitat monitoring and seabed mapping to infrastructure inspection and mine countermeasures. A fundamental challenge in this field is Coverage Path Planning (CPP), the problem of ensuring complete and efficient area coverage.

Discriminant validity and interrelations of conceptual and procedural knowledge in fractions and algebra: Evidence from confirmatory factor analysis

British Journal of Educational Psychology, EarlyView.
Abstract Background Conceptual and procedural knowledge are two distinct types of mathematical knowledge. Measuring them with sufficient discriminant validity is challenging because they are typically highly correlated. Prior studies have demonstrated discriminant validity of paper‐and‐pencil measures separately for fractions and algebra.

Design and Experimental Study of a Novel Fault Current Limiter [PDF]

, 2010
Limiting the short-circuit current effectively is of great importance to keep the safe and steady running of the power system. A novel fault current limiter (FCL) on the basis of a high speed switch and a triggered vacuum switch (TVS) is presented.

Analytical Modeling of Rotary Electromagnetic Fault Current Limiter

IEEE Access, 2023
Rotary electromagnetic fault current limiter (FCL) is an emerging technology for limiting fault currents in the power network. The device consists of two movable air-core spherical reactor rings (i.e., inner and outer rings).

Control Strategies for a Power Electronic Based Fault Current Limiter (FCL) in No-Fault Operation

RE&PQJ
Fault current limiters (FCL) in electrical power systems offer the opportunity to reduce short-circuit stresses to the system in the case of faults. But as electrical power systems are normally operated without faults most of the time, FCLs must not have negative effects during these periods of normal operation.
