A Fuzzy Approach for Overcurrent Relays Simulation [PDF]

open access: yes, 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 ...
