摘    要:总结了国际大停电事故教训,在此基础上指出:引发大面积停电的重要原因是连锁过载跳闸,缺乏输电断面的安全保护。阐明了输电断面的内涵,分析了输电断面安全性保护的任务即维持输电断面的完整性和输电能力、避免断面连锁过载跳闸,并指出实施输电断面安全性保护的实现条件和关键技术,包括输电断面的在线快速搜索,输电断面连锁过载的实时预测以及防止输电断面连锁跳闸的实时紧急控制。针对3项关键技术,提出了初步的解决方案,针对CEPRI36节点系统进行的算例表明了该方案的可行性。

关 键 词:电力系统  输电断面  连锁跳闸  实时控制  实时预测

Abstract:Cascading overload trip due to lack of transmission section protection is an important reason of large scale blackout. This paper first illustrates the meaning of transmission section and points out that the objective of transmission security protection is to maintain its integrality and transmission capacity, and to avoid cascading overload trip. In addition, the implement condition and key technology are discussed, which are online capture of transmission section, real-time prediction of cascading overload and real-time emergency control to avoid cascading trip. This paper has brought forward the primary scheme. Its validity is verified by the calculation result of CEPRI 36 test system.
Keywords:power system  transmission section  cascading trip  real-time control  real-time prediction
