Relay Protection Setting File Mapping Storage Method Based on Node Vector Encoding

This paper develops an efficient blockchain-integrated storage model for relay protection setting files. Targeting XML(eXtensible Markup Language) files with deep nesting, strong parameter coupling, and frequent iterations, the model enables on-chain storage. First, the XML document model and storage methodology are elaborated, defining the standardized format for setting files. Subsequently, an XML storage method based on node vector encoding is proposed, which maps XML elements to RDB(Relational DataBase) for management. Key nodes are selectively stored on-chain through hash verification codes for auditing purposes. Finally, performance testing validates the method's effectiveness in storage efficiency and query speed, laying the foundation for constructing a secure, tamper-resistant, and verifiable blockchain storage framework for protection setting files.
