摘　　要：文章对国外1000kV特高压(UHV)输电线路继电保护与监控系统的配置(如1000kV线路保护、母线保护、变压器保护、交流过电压保护、数据采集和控制单元、光学电压互感器的信号处理单元等)及其系统特征进行了详细分析。在此基础上提出我国1000kV特高压输电线路继电保护与监控系统的研究、设计和开发思路。The paper analyzed in detail the disposition of protection and supervisory system for 1 000 kV UHV power transmission line abroad, such as 1 000 kV transmission line protection, bus protection, transformer, AC over - voltage protection, data collection and control trait, signal handling unit for optical ~ltage transformer, and its system characteristics. Based on the above, the idea of research, design and development of protection and supervisory system for 1 000 kV UHV power transmission line in China is put forward.
