Digital Fiber Current Differential Protection of the Power Lines to Improve the Stability of the Application

摘要

optical fiber communications technology, digital fiber-optic current differential protection in the past to exclude protection of the traditional limitations, in the power system have been widely applied. In this paper, an analysis of light differential protection advantages, principle and influencing factors, and some examples of proof digital fiber current differential protection can really reflect the power system of transmission line failures, and fully meet the electricity system to relay the rapid, selective, sensitive, reliability requirements.
