Isolated power network topology analysis and its application in service restoration

According to the structural characteristics of isolated power network, practical models for power supply and distribution system, including source model, load model and line model, are defined. A new method of forming associated matrix is provided to on-line analyze the network topology. Combined with the global network simplified analysis, it is used to identify the affected devices in fault tracing. Based on the states of branches after system fault, the faults are handled for service restoration. Practice shows that the proposed algorithm can accurately and reliably describe and trace the topological structure of system.
