A fault current limiter (FCL) may be applied to assist the low-voltage ride-through (LVRT) of a doubly fed induction generator (DFIG). FCLs with fixed impedance, lack flexibility adjust their impedance adapt different LVRT scenarios. The direct switch-in and -out fixed-impedance FCL yields transient electromagnetic oscillations in DFIG, which need addressed. In this paper, variable-impedance is...

Fuzzy Counter Propagation Neural Network (FCPN) controller design is developed, for a class of nonlinear dynamical systems. In this process, the weight connecting between the instar and outstar, that is, input-hidden and hidden-output layer, respectively, is adjusted by using Fuzzy Competitive Learning (FCL). FCL paradigm adopts the principle of learning, which is used to calculate Best Matched...

While implementing a d iagnost ic expert system, FAITH, we have developed a new language, FCL, for c o n t r o l l i n g the f i r i n g of product ions. FCL grea t ly s i m p l i f i e s the task of the user to d i r ec t t h i s f i r i n g in a coherent and purposeful way without s a c r i f i c i n g some of the main advantages enjoyed by product ion systems.

Coated conductors are very promising for the design of novel and efficient Fault Current Limiter (FCL). However, before considering using them in a power grid, their thermal and electromagnetic behaviors in the presence of over-critical currents need to be investigated in details. In this context, we performed finite element magneto-thermal modeling of coated conductors under over-critical curr...

A deep neural network (DNN) includes variables whose values keep on changing with the training process until it reaches final point of convergence. These are co-efficient a polynomial expression to relate feature extraction process. In general, DNNs work in multiple ‘dimensions’ depending upon number channels and batches accounted for training. However, after execution before entering SoftMax o...

The authors deal with design and analysis of an air-core electromagnetic fault current limiter (FCL) rotary motion. proposed device is characterised by a simple structure, fast operating speed reversible operation. It consists two movable concentric air core spherical reactor rings (i.e. inner outer rings) variable mutual angular displacement. At normal condition, reactors are approximately ali...

Mining operations often produce large volumes of waste rock to access economically valuable mineralized zones. Waste is usually stored in surface piles, the construction and reclamation which represent a challenge for industry. A flow control layer (FCL) made crushed or sand constructed on top each bench could contribute water infiltration, thus improving pile stability limiting contamination. ...
