“Due to extreme temperature variations in the interior of Spain, there were anomalous oscillations in the very high voltage lines (400 kV), a phenomenon known as ‘induced atmospheric vibration’. These oscillations caused synchronisation failures between the electrical systems, leading to successive disturbances across the interconnected European network.”
The risks posed to electrical systems by big variations in atmospheric temperatures are well known in the industry, even if it is rare for problems to manifest on this scale.
“Due to the variation of the temperature, the parameters of the conductor change slightly,” said Taco Engelaar, managing director at Neara, a software provider to energy utilities. “It creates an imbalance in the frequency.”
Georg Zachmann, a senior fellow at Bruegel, a Brussels thinktank, saidthe system had suffered “cascading disconnections of power plants” – including one in France – when the frequency of the grid dropped below the European standard of 50Hz.
