This document provides settings and calculations for distance protection relays on a 220kV transmission line. These newly replaced relays has features of telecommunication, monitoring, control, and power swing blocking functions. Abstract: Accurate conditions monitoring and early wrong action warnings of relay protection in the Smart Substation is the basic guarantee to realize the normal operation of primary and secondary system of the power grid. At present, the traditional operation and maintenance monitoring methods of relay protections have poor timeliness, while some automatic monitoring methods have insuficient early warning performance, an lack the online. The documents presented should serve as a model to various utilities in preparing similar documents for setting protection relays installed installed at 220kV, 400kV and 765kV EHV and UHV transmission systems.
