摘　　要：目前电力网继电保护系统中的光纤通信接口主要使用C37.94标准,为使其安全有效地接入同步数字体系(Synchronous Digital Hierarchy,SDH)光传输网,提出了一种多模式保护倒换的方案,实现光口在不同工作条件下保护模式的灵活选择。该方案可以支持自动、手动、强制和锁定等操作模式。实验结果表明,该方案可以满足电力网中远端保护设备和复用设备间的光纤通信光口保护要求。The simultaneous existences of various fiber optic communication interface will reduce the insecurity in the relay protection system of power network. In order to effectively and safely access to the optical transmission network of Synchronous Digital Hierarchy（ SDH）,a novel scheme for multi- mode protection switching optical fiber communications is proposed for achieving the optical port’s flexible routing of protection model under different operating condition in this paper. The scheme can support kinds of operation modes including automatic,manual,mandatory and lock operation. The experiment results demonstrate that the proposed scheme can meet the requirements of fiber communication between remote protection equipment and multiplexing equipments in power network.
