Electricity supply Go to Spain and Portugal after the big darkness This caused confusion on the iPerian Peninsula. The blackout was muttered tunnel and railway Telephone service and internet connectionsAnd in some parts of France, ATMs and traffic lights were turned off. About 50 million people have been affected by darkness.
Spanish National Network Operator Red Electrics said in a statement on Monday night Electricity supply has been restored In some regions such as Catalonia, Andalusia, Bask Country and Castilla Y Leone.
Edwardo Preeto, the function of the Red Electric, declared that the situation was not the pioneers, and described the event as “exceptional and extraordinary”, while the European Commission’s Vice President of the European Commission, Teresa Ribra, in charge of promoting clean energy, while promoting clean energy.One of the most intense chapters recorded in Europe In recent times. “
Authorities continue to try Determine the exact cause of darknessBut experts have raised some hypotheses on why it happened. However, it must be pointed out that there are some evidence that allows you to confirm the failure at this time.
Potential network issues
London University’s Energy Stability Professor Onima Enduka explains it Electrical networks are usually interconnected This is because power plants are far from cities. This means that the cutting of electricity in one part of the network is “the effect of waterfall in other areas”.
“The ideal is Connect the layers on the systemAs many distribution points, reserve generators located in different places, such as interconnected cables “, explains.
The solution is that the energy companies will soon recover the power supply to the affected customers, but the practice of accomplishing this feat is “yet to be released”.
Portuguese officials quoted by ‘AP’ and local media have so far accused of blackout The technical issues specified He pointed out that it came from outside the country, but the investigation is still ongoing.
Cyberat was rejected by some, not by all
Junda de Andalusia’s president Juanma Morneo said on Monday Cyber attack is not rejected And is recommended to be cautious for citizens. However, cyber attack Has been denied by authorities such as Pedro SanchezThe President of the Spanish Government, Portugal’s Prime Minister, Louis Mandinigro and the European Council President Antonio Costa.
“Spain has methods to deal with these kinds of circumstances,” Sanchez posted on the social network. “Again, I call the citizens to cooperate and act with all the authorities With responsible and citizensLike we ever done. “
A rare atmospheric event?
Reports released on Monday suggest that blackout may have been the result of a rare event “Trigger atmospheric vibration”This caused “irregular swings” in the high voltage lines of the Spanish energy network.
“These oscillations caused synchronization failures among electrical systems, which leads to subsequent disruptions Interconnected European networks“As announced by Portuguese energy company Ren to the ‘BBC’ on Monday afternoon.
Ren later denied these reports in the Portuguese media. But,What are these vibrations What would have been on the region’s electric network?
Solomon Brown, Professor Solomon Brown of the University of Sheffield in the United Kingdom, confirms that a “trigger atmospheric vibration” can be considered the equivalent of a small change Local electromagnetic field“
Energy distributor can use a series of actions to control this, and he continued, which means that the amount of energy they provide to produce or reduce the amount of energy they provide.
In cases where the disruption is huge, Brown adds it Operators can turn off the network Run it slowly. Reporting energy on the network is “complex”, he added.
Although he is not an expert on Hispanic-portuguese network, Brown believes both “Interconnected with” with high voltage cables Sync to create a single electric phase.
“This is the most common. As for Europe, it helps to create a unique electric phase that can cooperate, but the tension must be managed separately and re.” He explains that.
“Such a common failure of the network is very unusual”
The National Portuguese Internet Security Center said in a statement that there were no signs of blackout due to cyber attack.
In the reports for ‘Euronaws’, experts in the Energy Infrastructure, the nearest general director Taco, said, Interconnected of national networks Its settings indicate that failure or attack can have the same net end.
“Such common failure of the network is very unusual and may be for many reasons: Physical failure on the network It will cause the fall of the delivery, Integrated cyberback Or a dramatic imbalance between the supply and the need to carry the network to the range, ”he explained.
“It’s about Failed by the computerThen between different regional and national networks can cause a large number of cuts we see. It can also be said about cyber attack: many of these organizations are incorporated and sharing property, ”he added.
