Power system protection at transmission and distribution levels based on overcurrent relays is essential based on their properties such as detection, stability, high speed, backup and error correction accuracy. Since distributed generation sources are connected to the power grid, they not only increase the short circuit level of the grid, but also disrupt the set point of main and backup relays...

The wind energy conversion technology of a Permanent Magnet Synchronous Generator (PMSG) is very promising in renewable power generation. However, the performance grid-connected PMSGs greatly affected by grid disturbances because their stator windings are interfaced with directly. There different Fault Current Limiter (FCL) topologies that capable improving Ride Through (FRT) capability PMSG tu...

40 LLE Review, Volume 89 The response of a superconductor to the injection of current pulses depends directly on the quasiparticle dynamics1 since the carriers injected from the external circuit are normal (unpaired) electrons that disturb the quasiparticle–Cooperpair dynamical equilibrium. Most commonly, a current pulse with an amplitude higher than the sample critical current Ic is used (supe...

this study investigated the potential role of age in inductive and deductive grammar learning among iranian foreign language learners. the experimental population consisted of our randomly selected samples including two groups of children (with age of exposure to english within 8-13), and two groups of adults (with age of exposure to english within 11-13). thus, the comparison was between ch...

This paper proposes the possible effect on the reduction of fault current and its protective coordination for upcoming smart grid. Fault levels in electrical distribution system are rising due to the increasing presence of distributed generation, and this rising trend is expected to continue in the future. Superconducting fault current limiter is a promising electrical equipment to reduce the e...
