Avoiding Blackouts
On 10 April 2004, a Psymetrix system was being used to monitor a national network when an oscillatory instability incident occurred. The oscillation rose quickly in amplitude, resulting in about 700 alarms being registered in the control centre, which was too many and too diverse a number for the operators to understand what the core problem really was.
The Psymetrix system, however, identified growing oscillations in the grid that were not damped, and exactly when the problem arose. Armed with this information, the operators were able to reverse a dispatch instruction that had taken effect when the problem arose, and this successfully stabilised the system.
It was the opinion of the Head of Control System Operations at the operator company that the Psymetrix system saved the power grid from a widespread blackout.
