基于光纤通讯的快速保护型配电自动化模式方案

摘要

该文列举目前在国内配电自动化系统应用的几种基于保护原理的配电自动化模式：常规线路保护、面保护、快速光纤纵差保护，比较分析这些模式的优缺点及其在配电自动化系统中的适应场合。综合应用了面保护及电流型配电自动化的特点，提出一种基于快速光纤通讯集中处理保护的配电自动化方案，试验及应用证明此方案不需要配电站出口断路器跳闸，大大缩短了非故障线路的停电时间，动作准确可靠。%This article is currently listed in the domestic distribution automation system application of several principles based on the protection of distribution automation modes:General line protection, face protection, fast fiber longitudinal differential protection, a comparative analysis of advantages and disadvantages of these models and its application in distribution automation system in the adaptation occasions. Integrated application of surface protection and current-mode characteristics of distribution automation is proposed based on fast fiber-optic communications to focus on the protection of power distribution automation, testing and application of this program does not require proof of export of electric sub-station circuit breaker tripping, greatly reducing the non-fault lines, power outages, action accurate and reliable.
