Scope

Scope: This document specifies the relay protection configuration and relay protection setting calculations for 110 kV to 220 kV local power grids. This document is applicable to 110 kV to 220 kV local power grids that include conventional power grid characteristics, frequent startups of heavy industrial loads, new energy transmission lines, multi-point T-connected transmission lines, and line-transformer combinations, among other application scenarios. For local power grids below 110 kV, this document can be used as a reference.
