On 10th February 2019, a blackout occurred and while restoring the system, an unexpected behavior happened on power stations with black start capabilities.

During the incident, units were started up and island formed around some of generating stations by connecting essential loads through 30 KV lines but at the time of connecting 110 kV electric line machine tripped with different alarms “loss of excitation, over speed, etc.”

For other power stations, machine was started but tripped immediately at first attempts of connecting load (before forming island).
