Home / Fiber Optic Upgrade of Relay Protection
This research will develop application guides and evaluate new technologies for improving relay settings and Configuration Management, reducing cost of protection system maintenance, and advancing new P&C design by embracing fiber optic communication and digital substation. 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. In order to prevent grade-jumping tripping in coal mine distribution network, based on the analysis of the causes of grade-jumping tripping, several schemes to prevent grade-jumping tripping are compared and analyzed, and the fiber current differential protection scheme is suitable for application. So Fibre optic provides great advantage for Solkor differential protection relaying. The OFC American Optical Communications and Optical Network Show will be held from March 7-9,2023 More advanced than iPhone 14, Qualcomm's "Breaking the Sky" technology was officially released and will be available soon!.
