A Sectionalizing Method in Power System Restoration Based on WAMS

Based on a minimal PMU installed network,the sectionalizing process is designed in such a way that resulted islands satisfy a variety of constraints(including the classic constraints of power system restoration planning as well as modern observability constraint of WAMS operation).And each island will be fully observable.When solving minimal PMU installed network and separately restorable islands,the application of the proposed algorithm on the New England 39 bus power system with 10 generators implies that the proposed analytic algorithm is useful in power system restoration planning.
