摘　　要：为进一步完善特高压电网安全理论和安全监控技术,基于实际电力系统大停电事件分析,讨论了形成连锁故障的条件和大电网停电事件的复杂性,解释了典型大规模停电事件发生和发展的机理,指出电力系统安全防御体系的缺陷是造成大规模停电的重要原因。在上述基础上,针对特高压大电网安全的关键问题,讨论了对特高压大电网安全防御体系的新的功能需求。最后建议建立分布式的多智能体安全监控系统,加强对发电机和关键输电线路的实时监测和提高电力系统危急状态实时调整能力,这样可以充分降低电力系统发生大规模电压崩溃的风险。Purpose of this study is to further consummate security theory and technology for UHV power grid supervision control. Based on analysis of actual power system blackouts, this paper discussed formation of cascading failure conditions and blackout complexity in large-scale power systems and explained occurrence and development mechanism of typical large-scale blackout event. Some defects of power system security defense system were important reasons causing blackouts. Based on above and according to key characteristics of UHV power grid security, new function requirements of UHV power grid security defense system were discussed. Finally, a security supervision control scheme of distributed multi-agent system is proposed to strengthen real-time monitoring for generators and key transmission lines and improve emergency adjustment ability in real-time for overall power system, so that massive power system voltage collapse risk could be fully reduced.
