摘　　要：提出了电力系统安全稳定综合防御体系的框架。从一般安全理念出发,电力系统安全稳定综合防御体系可由电力系统安全保障体系(即主动安全体系)和电力系统稳定控制系统(被动安全体系)构成。电力系统安全保障体系(主动安全)是指提高电力系统安全性和可控性的措施;电力系统稳定控制体系(被动安全)是指保证电力系统受到扰动后的安全性和稳定性的措施。电力系统安全保障体系(主动安全)可分为三道防线:第一道防线是坚强的电网结构,为电力系统安全奠定坚实基础;第二道防线是最优的自动控制系统,提升电力系统的安全运行水平;第三道防线是安全的运行方式,保证电力系统运行在安全水平。电力系统稳定控制体系(被动安全)就是传统的电力系统安全稳定三道防线,第一道防线是快速切除故障元件,防止故障扩大;第二道防线是采取稳定控制措施,保持系统稳定运行;第三道防线是系统失去稳定时,防止发生大面积停电。A framework of comprehensive defense architecture for power system security and stability is presented. From the general safety concept, the comprehensive defense architecture should include the power system security assurance system, i.e. active safety system, and power system stability control system, i.e. passive safety system. Power system security assurance system （active safety） refers to the measures to improve power system security and controllability. Power system stability control system （passive safety） refers to the measures to maintain power system security and stability during disturbances. The power system security assurance system （active safety） can be set to three-defense lines. The first defense line is a strong power grid structure, to lay a solid foundation for the power system security; the second defense line is the optimized automatic control system, to enhance the safe operation of power system; the third defense line is a safe operation planning to ensure that the power system operates at a safe level. Power system stability control system （passive safety） is the traditional three-defense lines for power system security and stability. The first defense line is rapid removal of faulty components, to prevent the failure to expand; the second defense line is the control measures to maintain power system stability; the third defense line is the measures to prevent widespread blackouts when power system loses stability.
