| Abstract | ||
| Single line to ground and double line to ground faults occurred in distribution power system which leads to high fault current that is returned to this system through earthing conductor. This paper proposed smart earthing technique to reduce this current. The fuzzy logic controller is used in this technique to increase or decrease the earthing resistance which connects the neutral of the substation transformer to the earth point depending on the measured faulted current. MATLAB/ Simulink is used to test the performance of this technique. This technique applied to (11) KV distribution power system model with real data from distribution substation in Karbala city. This smart earthing technique deals with any unsymmetrical earthing fault that occurs at any location in the distribution network with any fault resistance.ﻣﺔ ﺧﻄﺄ. | ||
