A Fuzzy Approach for Overcurrent Relays Simulation [PDF]
, 2003 Accurate models for Overcurrent relays (OC) with inverse time characteristics have an important role for efficient coordination of power system protection devices. This paper proposes a new method for modelling of OC relays based on fuzzy logic. The new model is more accurate than traditional models and has been validated by comparing it with the ...

Time overcurrent adaptive relay
International Journal of Electrical Power & Energy Systems, 2003 In this paper we recommend an inverse time overcurrent adaptive relay. This adaptive relay has a greater sensitivity and reduced operating times using only the information available at the relay's site. We herein describe the functional structure of the overcurrent adaptive relay, its implementation and the results obtained in laboratory tests with ...

Overcurrent Relay for Generation Distribution Utilization
ELEKTRIKA- Journal of Electrical Engineering, 2022 Distributed Generation (DG) is the production of electricity from a variety of renewable energy sources that is closer to the customer and load. The addition of distributed generation sources to the distribution networks alters the characteristics of distribution system and has an influence on its protection coordination.
