Abstract

Due to the different fault characteristics of the micro grid under the two kinds of operation mode, which are connected to the main grid and the isolated mode, and the various topological structure and the internal tide make for the traditional relay’ malfunction. The paper proposes a fault area localization scheme based on the node searches. The scheme uses the difference of the negative sequence phase of the bus bar feeder terminals as the judgment of the fault direction and then puts forwards a new search scheme for the fault area.
