摘要
分析了广域保护与传统继电保护的区别,指出广域保护能实现故障快速、可靠和精确切除,并能对系统进行实时在线安全分析;结合国内外该领域的发展情况,系统介绍了广域稳控系统和基于相角测量的保护的现状和相关实例;对广域保护的应用前景进行了展望,指出广域保护是未来系统保护的发展方向。
In this paper ,the differences between wide-area protection and traditional relay protection are explained firstly, getting a conclution that wide-area protection can achieve quick and accurate fault removal, and make real-time online safety analysis. Then with the latest development at home and abroad, research current status and some examples about special protection system and protection based on phasor measurement unit are presented. Finally, the paper points out the development trends about wide-area protection in the future.
