摘要：The algorithms for choosing the minimum number of PMUs of two types have been developed.The PMUs are to be placed at nodes and tie lines in power systems to provide topological observability of power systems under normal operating conditions and ensure reliability of topological observability in case of failure of individual tie lines and PMUs,in the absence and presence of conventional measurements.The developed algorithms are implemented in the MATLAB environment.Their efficiency has been proved by computations for a large number of test IEEE schemes and real power systems.
