摘　　要：由连锁故障导致的大停电多数经历了一个明显的故障发生发展的过程,在此期间如采取合理控制措施,有可能避免大停电的发生。从我国多年电力建设的经验出发,借鉴多智能体系统理论,提出了具有工程实践意义的,基于"离线断面功率传输极限分析"的广域协同预控制系统框架。算例结果表明,该系统对局部区域连锁故障可能导致的全网失稳起到预防的作用。Major blackouts caused by cascading failure experienced an observable process of equipment outages. Blackout could be avoided if reasonable control measures were taken during that period. Started from the experience of electric power construction in China for many years and used multi-Agent system theory for reference, a wide area cooperative precontrol system framework based on off-line analysis of cross-section power transfer limit is presented in this paper, which is feasible for engineering practice. Case study shows that the wide area cooperative precontrol system can prevent grid instability triggered by cascading failure occurring in local area.
