The protection of high voltage direct current (HVDC) grids is a challenge considering that the system must detect, locate, and interrupt large fault currents in few milliseconds. Resistive type superconducting limiters (R-SFCL) can help solve difficult task, reducing extremely demanding ratings HVDC circuit breakers. This paper presents different approaches to model R-SFCLs order analyze their ...

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...

Smart grid is the most significant topic in power system due to numerous benefits. integration of distributed generation. DG plays an important role different configurations either connected mode or islanded mode. Multiple will result fault currents this may lead damage existing protective devices. In paper Fuzzy used optimally locate and Jaya a new optimization technique adapted size Fault cur...
