Research On Smart Grid Fault Analysis Based On Simultaneous Fault Detection

The communications between smart grid nodes and the core network are frequently requested in smart grid. This kind of communications results in complicit power transmission paths. The paths may be time varying. The change of connections triggers the change of connections of circuits. Finally, the smart grid protection method is changed because of these frequent changes at connections of circuits. To solve the problem of the dynamic environment of grid deployment and connections, some reliable fault protection method is requested to enhance the stability of smart grid. A Smart Grid Fault Analysis based on Simultaneous Fault Detection (FASFD) is proposed in this paper. FASFD could deal with faults very efficiently. To evaluate FASFD, an experimental circuit is set up. The test results show that FASFD could raise the ability of fast fault recovery.
