构建大电网安全防御体系——欧洲大停电事故的分析及思考

Constructing Wide-area Security Defensive System in Bulk Power Grid——A Pondering over the Large-scale Blackout in the European Power Grid on November 4

欧洲电网2006年11月4日大面积停电事故起源于德国电网内一条线路的停运。文中简要介绍了线路停运前系统的运行状态及事故的发展过程,多方面分析了产生事故的原因,指出了欧洲电网暴露的问题,总结了经验和教训,探讨了构建大电网安全防御体系的几个方面。

On November 4, 2006, at around 22：10 the European interconnected grid was affected by a serious incident originated from the disconnection of a 380 kV line in the North German grid. The paper provides a brief description of the prefault system operation and of the main events that triggered the blackout, identifying some of the main causes that resulted in the separation of the European power grid and the blackout. In addition, issues related to the European power grid and lessons on the blackout are discussed. Some relevant.measures are proposed to prevent large-scale blackout and construct the security defensive System in bulk power grid in China.
