초록

This paper presents an adaptive overcurrent relay applied to interconnecting wind generators in distribution networks. When a fault occurs in the case of the decreasing the wind power generator output, the conventional overcurrent relay can't detect the fault. The suggested adaptive overcurrent relay can detect. An adaptive overcurrent relay improves reliability and security of the power system protection with distributed generator APSCAD/EMTDC simulation results have shown effectiveness of the proposed method.
