Abstract

This paper proposed the reclosing method in distribution system with battery energy storage system (BESS) using wavelet transform (WT). The proposed method performs the WT of load current and then calculates the absolute value of slope of detail coefficient. The mother wavelet used is db4 of level 6. The fault clearing is detected using the rapid increase of this value. After the detection of fault clearing, the reclosing is performed. To verify the proposed method, various simulations according to the fault clearing times, fault resistances, and fault lengths are performed using EMTP. The simulation results show that fault clearing can be detected using proposed absolute value of slope of detail coefficient and hence the reclosing can be performed successfully.
