| Abstract: | For an example of wide area relaying protection,the wide area current differential protection is studied concretely,includingitsstructure,action criterion,algorithm,N-1operationstatuses etc.Thewidearea protection algorithm based on graph theory was inspected by IEEE 5 nodes power system.The relaying protection N-1 operation statuses were analyzed and the strategy based on wide area information was proposed.The criterion and the algorithm are simple and convenient for fault determination.The fault estimation... |
