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. 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. Utilities face the challenge of managing the performance and reliability of multi-generation protection and control (P&C) assets accompanied by tighter regulations. As part of the Universal Relay (UR) family, the F60 features high-performance protection, expandable I/O options, integrated monitoring and metering, high-speed comm o detect high-impedance faults, such as downed conductor. ronous 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. Abstract—This paper documents a collaborative effort between the authors' companies to design three separate centralized protection and control (CPC) systems for an existing distribution substation. The first uses a powerful but traditional approach with a microprocessor relay, the second a.
