广东电网光纤保护方案的论证

广东电力系统的电力光纤网络初具规模，一个以珠江三角洲为中心的光纤网已经形成。如何基于该网络来发展光纤保护是目前继电保护所研究的课题之一。广东电力网光缆的芯数资源有限，既要满足语音通信的需要，也要满足数据通信的需要，还要考虑社会的需求，继电保护如何使用现有资源才是合理而又经济，该文通过对目前的广东电力光纤网和继电保护情况的分析，寻求最佳方案。

Discussion on optical protection planning of power network in Guangdong

At present, the optical cable network used in power system of Guangdong province has been taken shape a network around Zhujiang delia has been set up. So how to develop the power protection based on the optical network becomes a problem that is needed to study at present. Due to the resource of cores in the optical cable network of Guangdong province is limited, and need to fulfill the demand of voice and data telecommunication, at the same time, the requirement of society also needed to be included. How to utilize the existing resource in power protection and make it reasonable and economical is the main problem. This paper analysises the optical cable network and protection system in Guangdong province, and presents the best scheme.
