A centralized wide-area backup protection system for substation, in which the information redundancy is implemented based on direction and distance information, is proposed. By means of incidence matrix the fault tolerance of information is implemented to judge the fault. The architecture and working principle of wide-area backup protection system are presented, and the processing method of redundant information is researched, i.e., according to real-time topology of power network the formation strategy for draft node-branch incidence matrix, direction incidence matrix, direction incidence matrix and composite incidence matrix is drafted. Simulations for different types of faults are performed, and the strategy of the proposed wide-area backup protection system to cope with special circumstances is put forward.
