With the development of synchronized sampling technique and other advanced measurement approaches, the merging of various substation data to be used in new applications in the EMS solutions has not yet been explored adequately. This paper deals with the integration of time correlated information from Phasor Measurement Units, SCADA and non-operational data captured by other intelligent electronic devices such as protective relays and digital fault recorders, as well as their applications in alarm processing, fault location and cascading event analysis. A set of new control center visualization tools shows that the merging of PMU, operational and non-operational data could improve the effectiveness of alarm processing, accuracy of fault location and ability to detect cascades. © 2010 IEEE.
