文 | 中关村储能产业技术联盟综合整理 据央视新闻4月29日报道,西班牙和葡萄牙28日遭遇大规模停电,影响超过5000万伊比利亚半岛民众,交通、通信、医疗等关键领域一度瘫痪, 法国南部等周边地区也受短暂波及。 欧盟委员会执行副主席里贝拉表示,目前无任何证据表明导致伊比利亚半岛大面积停电的原因是网络攻击。此次大停电是近年来欧洲记录到的 最 严重停电事件之一。 目前,官方尚未给出正式的停电原因,仍需时日调查确定。 西班牙电网运营商Red Eléctrica 负责人Eduardo Prieto 4月28日表示:停电由"电网的强烈振荡"引发,该振荡导致西班牙电力系统与欧洲电网断 开。他提到的"强烈震荡",也就是首相桑切斯在讲话中提到的"技术层面出现重大波动"。 功率开始快速变化时,就会引起电网的振荡,最终导致崩溃停电。比如,大规模负荷接入或切除会引起发电功率和负荷需求之间的不平衡,导致 电网振荡出现。 葡萄牙电网运营商REN认为 :电网的这次异常振荡可能与西班牙的极端气温变化有关。该公司专家称,极端气温波动导致了400kV以上的超高压 电网振荡。 能源分析师表示,如此大规模的停电在富裕国家并不常见,鉴于伊比利亚半岛对 ...
