Substation Topology Analysis Based on Improved Tracking Algorithm

The substation network topology analysis is an important part of power system network topology, which occupies a large number of total time of topology analysis. Improving the topology analysis efficiency is the key to ensure the rapidity of the power system network topology. The chapter first summarizes the main methods applied to the power system network topology analysis. Second, it proposes an improved tracking algorithm based on the analysis of two shortages in the existing tracking algorithm. Finally, the simulation results validate that the proposed algorithm for substation network topology analysis is easy to be practiced fleetly. There are only three steps for calculation when the network nodes are connected, which improves the speed of the network state estimation tremendously.
