European electrical networks suffered two vitality oscillations about half-hour earlier than the good blackout within the Peninsula | Economy | EUROtoday

The analysis of European electrical networks (ETSO-E, for its acronym in English) has began. This Friday the group that teams them has designated the group of specialists who will probably be in command of the investigation, which will probably be led by the Austrian Klaus Kaschnitz and the Hungarian Richard Balog. In the outline of info earlier than the blackout, it occurred on Monday, April 28 at 12.33 minutes, the community managers stand out that there have been two oscillations “of power and frequency in the European system, in the main areas of continental Europe”, offering some components to this point unknown.

The two oscillations described by the Entso-E assertion between 12.03 and 12.07 of midday, in keeping with the time of the Iberian Peninsula, and 12.19 and 12.21, explains the assertion launched this Friday. Porteriorly, “at the time of the incident, there were no oscillations and the variables of the electrical system were within the normal functioning range,” the community managers level out. “Before the incident, Spain’s international exchange programs were 1,000 MW with France, 2,000 MW with Portugal and 800 MW with Morocco, all of them in the exporter,” he particulars.

About half-hour after the primary oscillation started, the intense drawback started in Spain, not in Portugal, though later the issue prolonged: “From 12:32:57 and in the following 20 seconds, a series of different generation shooting in southern Spain were presumably recorded, for a total initially estimated total of 2,200 MW. In Portugal and France concrete facts.

From that moment on, a sequence of facts began that ended the collapse of the electric Iberian system. “As soon as the interruption of the electricity supply occurred, the affected network managers worked together in a coordinated effort to restore the supply in the affected region of France [al sur del país]as well as in Spain and Portugal. ”

The enumeration of info continues to clarify the method of restoration of the electrical energy community within the Peninsula, which started by the restoration of the connection between Spain and France at 12 and 44 minutes. From right here started a restoration course of that ended at 4 within the morning with “the complete restoration of the network transmission process in Spain.”

Two phases analysis

In addition to the sequence of what occurred, the group that teams the managers of European networks as a Red Eléctrica de España explains that “the research will be divided into two phases.” “In the first place, it will collect and analyze all the available data on the incident to rebuild the events of April 28 and determine the causes of the blackout. These conclusions will be completed and published in a factual report,” he says. As defined by the spokesmen of the European Commission, this primary half needs to be prepared in half a 12 months.

“In the second phase, the panel [de expertos] It will establish the recommendations that help prevent similar incidents in the future, which will be published as a final report, ”explains the assertion, through which it isn’t specified how lengthy it may well take.

The designation of two specialists who lead the group, one from Austria and one other from Hungary, exterior the international locations concerned within the nice blackout (Spain, Portugal and France) conforms to what the European Commission introduced the day after the shaking.

The quick precedent to what occurred in Spain and Portugal on April 28 was the partial blackout of June 21 of final 12 months a number of international locations of the Western Balkans (Albania, Bosnia-Herzegovina, Croatia and Montenegro). This occasion was not as critical as that of the Iberian Peninsula. However, there was additionally an Entso-E skilled panel that was created on July 15, 2024, lower than a month after the partial blackout. Now it has not taken two weeks to create that staff.

The closing report was printed on February 24, eight months after the incident. The reason behind the issue had been two first quick circuits attributable to “the vegetation that grew too close to the power lines.” Therefore, one of many major suggestions was additionally “to review the procedure for the control of vegetation growth” to “guarantee adequate pruning” as a “crucial element to avoid short circuits and maintain a safe and reliable electrical grid.” The fee has not but pronounced, since it’s nonetheless finding out the conclusions.
