Abstract

In this paper, model of overcurrent relay (OCR) characteristic curves using adaptive neuro fuzzy inference system (ANFIS) are proposed. The OCR characteristic curves playan important role for protection coordination of power system. Model of OCR characteristic curves are appropriate with IEC standard. This model implementsof microcontroller ATmega 128 as digital relay and personal computer as facility to design of OCR characteristic curves. Input for training to OCR characteristic curves using IL/ISand TCB. ANFIS is developed with different types of membership function and each membership function is trained for 10 iterations. ANFIS is developed using visual basic.The simulation results are compared with different types of membership function to obtain the optimal design of OCR characteristic curves. Moreover, the testing results are compare with IEC standard curve to check validation and accuracy of the proposed model.
