The Black box With all the blackout data, registered by Red Eléctrica, it is already in the hands of the Commission for the analysis of the electricity crisis. Now a forensic work process begins with thousands and thousands of values that threw the more than 60,000 generating plants and 10,000 Arrivals (positions) of electricity in substations in Spain.
A total of 70,000 critical points showing data every 20 milliseconds. What was the first to fail? How did the rest answer? Was there support? When did the European disconnection occur exactly? A part of the answers is in the data of that Black box of Electric Red, although surely we will have to go further.
This will be the work forensic That arrives now and can be extended for days. At the moment, some basic data is known that have announced Red Eléctrica, the Government and the records that can be publicly consulted with the Gracadar API, which monitors some of these second to second critical points.
At the moment, it seems clear that there were five key seconds in the history of the blackout. Between 12:33:16 and 12:33:21. This is the chronology of what is known. But refine the millisecond can be key in the investigation to determine where and how everything began.
Between the second 16 and 17, there were something more than a second and a half whose milliseconds will have to be analyzed with magnifying glass in the black box of Red Eléctrica. Even if before there were clear indications of instability, as it seems.
The morning began normally. The photovoltaic entered strongly into the mix around 8:00. The frequency of the network was slightly below 50 Hz at 12:20, but in rank. Until….

The frequency falls suddenly, in an event whose Red Electric origin places in the southwest peninsular. The network remains stable but slightly below 50 Hz frequency for 1.5 seconds.
⚠ Second event ⚠
It also has origin in that area of the Peninsula. It is not yet known if there is a relationship between both failures. That begins an unrecoverable fall slope that seems to jump international connections.
In the four second seconds there is an accelerated drop in frequency and tension. Surely because of the disconnection of the European network. And everything else, in waterfall. You can no longer replenish.
The Peninsula It goes black automatically.
Just before, The photovoltaic was majority (which is not the same as being culpable of the blackout). Hydraulics was the one that was best stabilizing the system. But something happened. After the fall, solar and wind lack inertia to return to start up The system. So they begin to pull hydroelectric and combined cycle, especially for that task.
