Abstract
With the development of large grid, distributed, heterogeneous complex power network, the power grid management is more and more complex and its safety operation is more important. In order to effective control of power systems in normal operating conditions within the shortest possible time, the relay signal must be accurately passed to the communication terminal by the transmission channel. At present, optical fiber protection channel is widely used in many parts in China. It also has some problems, such as leakage of immature technology, lack of synchronous optical transmission signal protection performance indicators. In this paper, the basic content of relay protection is described, the application of optical fiber communication technology, as well as the problems exposed in the practical application in the signal transmission channel is introduced, the development prospect of new technologies and materials for optical fiber communication technology is analyzed.
