Control center alarms for power systems usually arrive with low latency, quickly overwhelming operators. Previous approaches to dealing with alarm ordering include logical grouping (suppression and filtering) of alarms according to pre-defined rules and presentation of the resulting alarms to the operator.

With advances in synchrophasor (PMU) technology, we have an opportunity to enhance power system monitoring and control schemes. In this paper, we discuss how this can be achieved in two ways: 1) combining PMU measurements with spatial and temporal knowledge of the grid to classify the severity of an alarm and 2) intelligently ordering alarms with associated recommendations to enable operators to take...
