Application of synchronized monitoring for dynamic performance analysis Monitoring Power System Dynamic Performance Using Synchronized Sampling

The use of synchronized sampling technology is currently under rapid development in various areas of power systems. This paper reports on the latest development, demonstration and deployment efforts related to the uses of synchronized sampling technology and associated applications to improve power system monitoring during switching sequences, faults, cascading disturbances and other types of alert or emergency situations that may jeopardize power system reliability or security. The proposed efforts are aimed at improving verification of switching sequences, interpretation of alarms, reduction of state estimation errors, assessment of equipment status, etc. The new developments are illustrated using examples of improved existing, as well as new applications.
