| 摘 要： | 针对近年发生的电网大面积停电事故的问题，阐述后备保护存在的必要性以及安全自动化装置的作用，并针对两者配合方面存在的不足，提出了一种后备保护与安全自动装置协调工作的方案，在方案中引入了闭环控制体系和反时限自适应元件进行协调防御的反时限切除过负荷的方法。采用BPA软件对实际系统进行仿真计算，证明该方法有利于加强电力系统的安全稳定性。

| Abstract: | This paper analyzes the reasons of several international significant blackouts in recent years. Then the necessity of back-up protection and the function of automatic safety device are described. On account of their deficiency, a coordination scheme of back-up protection and automatic safety device is proposed, which contains closed loop control structure and inverse-time self-adaptive element for inverse-time load shedding. Based on the simulation of the practical system by BPA, it is proved that the scheme can strengthen the safety and stability of power grid effectively. |
