This April 28 Monday unprecedented electric blackout It is considered to be messy in many parts of our daily life: Traffic lights have been removedUnemployed Traffic, Internet Link and Telecommunication …. Things are gradually returning to normal, although it is still resolved One of the unknown people who are not worried about a large number of people in Spain: What is the reason?
That’s more as soon as possible Confirm the firm appearance of this incidentNo hypothesis has been rejected as stated by the president of the government, Cotton sanchezLast night. “They have suddenly lost, five seconds, 15 gigawat In the energy that occurs at that time, it is equal to 60% of the light consumed. This is something that never happens“I commented.
According to the sanses, the researchers They could not determine what the “missing” trigger of MW. “This is something that is still unprecedented by experts, but they will do No hypothesis is rejected.
A source indicates ‘stimulated atmospheric vibration’
The news was flying soon, about what this darkness would have triggered. In fact, one of the most strengths mentioned An atmospheric phenomenon is the potential cause of crisis. Portuguese operator is a source that is attached to the Networks (Ren), which has been pointed out in the reasons where it exists Stimulated atmospheric vibrationAccording to BBC and Reuters.
However, no official evidence has confirmed it and the Portugal company has finished Start a statement to deny it. Jovov Kansikao, a member of the Ren Directors Committee, spoke about A.The largest oscillation in the electric voltagesAt first, in the Spanish system, then extended to the Portuguese system, “the cause was caused by the event, without commenting on any occasion.
What is triggered atmospheric vibration?
The most rare event of the trigger atmospheric vibration This usually occurs when sudden temperature changes cause irregular movements in high voltage cables, such as the wind created. These vibrations can be summarized or interfered with electromagnetic fields, with important systems, such as high voltage electrical networks. If they spread with enough intensity, something unusual, they can Create a network instability, and, as a result, can cause supply cuts.
How can this affect the electric grid?
The European electricity is very interconnected and automatic. This means that if an anomaly that can put the stability of the system at risk – for example, the unexpected swing in frequency or tension – the security systems immediately respond to the major damage. Sometimes ,,, This response refers to the barrier disconnection It can cause or cause common darkness.
Is it common?
No. Trigger atmospheric vibrations usually do not take directly responsible Electric cuts, but its influence in technology systems is documented, especially in high sensitivity environments such as air traffic, telecommunications or satellite navigation.
In the case of electrical networks and more specifically, this is a impossible reason, as physicist and professor Mario Picasso noted Neutral“Must have been Air or sudden thermal changes“, They did not occur (brushing the nights close to zero degrees and a maximum of 20ºC or 25ºC),” It would be very strange. “
