This paper first review the OO model for electrical topological expression in paper [1]. After that using the object - oriented analysis (OOA ) methodology analyze the fast tracking of station and electrical network topology. A crucial method - - the heuristic network partioning method are pro- posed that reduces the compution burden (computing time and storage requirement ) of search in depth and width and matrix calculation.

A new method to fast trace power networktopology in which the graph theory is integrated with artificialsearch technique is proposed. In this method the node-breakerincidence matrix is used to express the topology inside thesubstation and through deducing node-breaker incidence matrixthe node adjacent matrix expressing the connectivity amongnodes is obtained and a node tree is constructed to represent theconnection of network nodes. Under real-time continuousoperation situation when switching event of circuit breakeroccurs, the proposed method can rapidly trace the topologychange within the substation by modifying the node adjacentmatrix and the nodes inside the substation are anew groupedand mapped as the nodes of power network, then usingheuristic search algorithm the former search tree are locallyupdated, thus the rapid tracking of local power network wherethe topology is changed is implemented. The test results of anactual power network show that the proposed method possessesversatility and real-time performance and can meet the need ofreal-time topological analysis of power network.
