Research on a new configuration method for transformer protection in intelligent substations based on communication addresses
At present,the configuration of virtual terminals in intelligent substations typically relies on manual matc-hing 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 transform-er protection configuration in intelligent substations,exploring communication configurations and the principles of auto-matic 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 configura-tions,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 substa-tions is proved.
