Harmonic Effects on Electromechanical Overcurrent Relays [PDF]
Doğuş Üniversitesi Dergisi, 2005 Elektromekanik asiri akim koruma roleleri sinusoidal akim altinda calismak uzere tasarlanmistir. Bu rolelerin harmonikli akimda calismalari guvenilir degildir. Literaturde harmonikler ve rolelerle ilgili pek cok teorik calisma bulunmaktadir. Bu makalede, harmoniklerin elektromekanik ters zamanli asiri akim rolesinin (TZAAR) calismasina etkileri ...

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 ...
