SDH技术在电力系统智能变电站中的应用

Application of SDH technology in Intelligent Substation of Power System

现代化智能变电站要求传送的信息不仅是模拟信号,而且包括文字、数据、图像和视频等数字信号。同步数字体系(Synchronous Digital Hierarchy,SDH)技术经过映射、定位和复用等过程,实现电力系统智能变电站中音频、视频等信号的可靠传输。这不仅可完成电力系统变电站之间的可靠通信,而且可解决电力系统中各端站的总体调度问题。基于此,针对SDH技术在电力系统智能变电站中的应用展开探讨。

The information that modern intelligent substation needs to transmit is not only analog signals,but also digital signals such as text,data,image and video.Through the process of mapping,positioning and multiplexing,SDH technology realizes the reliable transmission of audio,video and other signals in the power system intelligent substation.It not only completes the reliable communication between the power system substations,but also solves the overall scheduling problem of each end station in the power system.Based on this,the application of SDH technology in power system intelligent substation was discussed.
