Abstract

Aiming at the problems existing in micro-grid, a set ofprotection schemes, which are according to the faultcharacteristics of micro-grid system with differentvoltage levels of 10kV and 400V in distribution network,are proposed in this paper. According to the simulationresults, it is verified that the protection scheme candetect various fault types of micro-grid in differentvoltage levels. The protection scheme has good rapidity,reliability and selectivity.
