Abstract

At present

the configuration of virtual terminals in intelligent substations typically relies on manual matching methods

which suggests a need for improving the level of automation.Therefore

a new approach to configuring transformer protection in intelligent substations is proposed.This study discusses the method for implementing transformer protection configuration in intelligent substations

exploring communication configurations and the principles of automatic identification for message publishing and subscription among intelligent devices.It also outlines the trend and rationale for new configurations of transformer protection in intelligent substations.Based on the interval information flow for 220 kV transformers

the paper deeply analyzes the implementation method of new transformer protection configurations

communication link parameter settings

the number of dataset entries

and standardized definition of descriptions.Moreover

it examines the modification and verification of related transformer protection parameters when expanding the medium-voltage side of transformers.Through the analysis of the medium-voltage side interval model of transformers

the feasibility of the new communication address-based configuration method for transformer protection in intelligent substations is proved.
