2025年4月西班牙和葡萄牙的大规模停电, 由连带高压造成, 影响数百万人, 也是欧洲20多年来最大的停电。 A massive April 2025 blackout in Spain and Portugal, caused by cascading overvoltages, affected millions and is Europe’s largest outage in over 20 years.

2025年4月28日重大停电, 影响西班牙和葡萄牙数百万人, 标志着二十多年来欧洲最大的停电, A major blackout on April 28, 2025, affected millions across Spain and Portugal, marking Europe’s largest power outage in over two decades and the first known event caused by excessive voltage. 欧洲电网运营商ENTSO-E认为,分层超压是直接原因,没有证据表明,由于可再生能源一体化,出现了网络攻击或失败。 The European grid operator ENTSO-E identified cascading overvoltages as the immediate cause, with no evidence of cyberattacks or failure due to renewable energy integration. 断电中断了运输、通信和银行服务,导致旅行者受困,服务普遍中断。 The outage disrupted transportation, communications, and banking services, leading to stranded travelers and widespread service outages. 虽然葡萄牙的电压控制系统运作正常,但西班牙的电压控制系统失灵,由于一些电力供应商提供的信息不完整,数据缺口依然存在。 While voltage control systems functioned in Portugal, they failed in Spain, and data gaps remain due to incomplete information from some power providers. 预计2026年初将提出最终的根源原因报告。 A final root-cause report is expected in early 2026.
