摘要
叙述了2011年9月8日在美国西南地区电网发生的大停电事故演化过程,从连锁故障防控的视角分析了事故发展的技术原因,包括安全分析和预防控制技术欠缺、实时状态觉知能力不足、保护定值整定不合理、控制方案设置不当和保护与控制动作不协调。凝练了连锁故障防控技术需要加强的基础性工作,指出必须全面、深入、及时地掌握系统动态特性,协调保护控制动作,提高仿真分析精度。
Based on the 2011 Southwest America blackout inquiry report, this paper presents a description of the event evolution and an analysis of technical causes leading to the cascade development from the point of view of prevention and control of cascading outages, including ineffectiveness of security analysis and preventive control, inadequacy of real-time situational awareness, unreasonabilitp of protection relay settings, inappropriateness of control system design and lack of coordination between protection and control. It concludes that several fundamental measures need to be strengthened, including a complete, thorough and timely understanding of system dynamic characteristics, coordination of protection and control actions, and improvement of simulation analysis.
