Practical Method Of Power Network Topology Analysis Based On Switch Classification

A practical method of power network topology analysis based on switch classification is proposed, achieving valid cooperation between substation topology analysis and system topology analysis, thus improving practicability of power network topology analysis, and avoiding substation topology analysis for unchanged substation, thus improving analysis efficiency. First, switch is classified according to its affection on grid topology. Second, substation topology analysis model and system topology analysis model are put forward. Then, the coordination between substation topology analysis and system topology analysis is studied, based on which power network topology analysis method is constructed. Finally, the proposed method is proved to be effective and efficient by applying to some power network.
