Abstract :
Nowadays, utilization of distributed generation (DG) has been enhanced because of its advantages such as increase of the
reliability, decrease of losses, enhancement of the line capacity, and less environment pollution. Protection of
microgrids, which consists of these generation sources, is one of the most essential concerns of distribution operators.
One of the most important issues in this field is protection of microgrid against the permanent and transient faults which
improves the reliability of the network. Moreover, wrong detection of these faults can inflict the immense costs to the
system. The conventional method in which recloser system was used, had some disadvantages. In this research, an
appropriate method has been proposed to detect and remove the faults using wavelet transform.that the mentioned
problems have been relieved intensively in the method.
