摘要
为提高电力系统继电保护光纤通道的可靠性,文章根据浙江电网220kV及以上电力线路继电保护光纤通道的现状及存在问题,分析了专用芯保护、复用保护、本线OPGW承载和迂回复用方式等几种通道配置方式的优缺点,并在此基础上提出了2条专用芯、一专一复和利用双口保护3种典型的通道在不同条件下配置方式,并给出具体的配置建议。
To improve the reliability of relay protection the situations and issues of relay protection fiber channels fiber channels of power system, this paper introduces applied to power lines over 220 kV in Zhejiang power grid, analyzes their advantages and disadvantages of several channel configuration modes including private protection, multiplex protection, OPGW-based same line and circuitous multiplex. Considering the above analysis, this paper puts forward configuration modes for three typical channels including two private fiber channels, one private channel and one multiplex channel, and adoption of protection equipment with two transmission interfaces respectively, further gives specific configuration suggestions.
