In this paper, a protection system adopting a MultiAgent concept for the distribution systems is proposed. An overcurrent relay(OCR) is developed as an agent by adding its own intelligence, self-tuning and communication ability. The proposed OCR agent is able to detect a fault or a change in the network in an autonomous manner and changes its operating parameters adapting to the new operation c...

This paper presents an overview of solutions proposed in the literature for the overcurrent relay coordination problem in the presence of distributed generators (DGs). Furthermore, several protection issues are identified to study the requirements for protection in the presence of DGs, and possible innovative solutions for resolving the operational conflicts between distribution networks and DG...

A Fano Factor-based adaptive overcurrent protection scheme, that automatically adjusts the settings in response to prevailing conditions of power system, is presented. Both phase and ground relays are based on same mathematical algorithm calculate operating time using Factors (FFs) estimated for current signals, respectively. Effectiveness proposed method validated various fault types under a p...

In modern protection system the key challenge is the trade-off between the security demand (no false tripping), the speed of operations and the dependability requirements. To meet this challenge properly, the application of a novel Artificial Intelligence (AI) method, using fuzzy logic, in power system protection has been proposed in this paper along with the simulated data. The examined techni...

Abstract The main goal of this study is to propose new characteristics an REF 615 model (overcurrent and earth fault relay) that used for feeder protection in actual radial system Egyptian Substation. When studying current, both light heavy loads as well locations are considered based on the nature network. proposed algorithm relies simultaneously activating three settings OC relay, with being ...
