PMU versus SCADA Video Events Summary March 2014 NASPI Control Room Solutions Task team Meeting
Event 1: Video files RTDMS_P MU_vs_SCADA_naspi1.wmv We had an issue on our 138 Kv system associated with new controls were being tested on a 65 MW max rated gas turbine. When enabled the controls caused the unit output to swing rapidly for approximately 30 seconds and also caused small scale voltage oscillations on the system. Eventually the unit was taken offline and the problems ceased. The event data in the replay is the line current and bus voltage as recorded by a PMU at the substation monitoring one of the two 138 Kv lines leaving the substation and an RTU at the same substation scanned every 4 seconds.
