Topology Analysis

Power system topology analysis is mainly focused on the classification of buses and electrical islands according to the switch status. It plays a crucial role in the energy management systems (EMS) and the distribution management systems (DMS). This chapter introduces a substation area protection topology analysis scheme and a wide area protection topology analysis scheme. The proposed schemes have obvious advantages concerning the amount of computation, and can guarantee fast tracking of the switch status. Compared with existing topology analysis methods, the proposed methods can improve the speed and accuracy of power network topology analysis. The chapter also introduces a new method for topology fault identification. This method could realize wide area topology identification in the case of a single topological error, multiple topological errors and multiple undesirable data. To further improve the ability to identify topology faults, undesirable data need to be identified effectively, and corrected.
