Today’s LiveWire Spotlight assesses NERC’s Lessons Learned addressing five cases where a state estimator (SE) or real-time contingency analysis (RTCA) failure could have been detected and dealt with more quickly if enhanced alarming were in place. The document offers a series of questions that designers should ask themselves as they customize the RTCA and SE alarm structure that best aligns with the responsibilities of the Control Room operators.

The loss of situational awareness for any reason is one of NERC’s top reliability concerns. Severe penalties may be levied if an electric system outage occurs, and it is found that an Operator did not act upon these Lessons Learned.
