State Grid Deploys Blockchain Technology and Files Patent for "Power Grid Model Data Management System and Method"

The State Intellectual Property Office of China shows that State Grid Corporation of China's North China Branch and Beijing Dianlian Technology Co., Ltd. jointly filed a patent for "a power grid model data management system and method", with the publication number CN118822450A, filed in July 2024. This patent involves blockchain technology and aims to address the security and reliability issues of traditional power grid model data management systems, and to achieve unified global management of power grid model data.

The patent abstract shows that the system consists of five core modules: data onboarding module, data maintenance module, data auditing module, data synchronization module, and data subscription module.

The data onboarding module is responsible for synchronizing power grid model data to all blockchain nodes, ensuring data consistency across the distributed network. The data maintenance module is responsible for maintaining power grid model data stored in the state database, such as updating and deleting. The data auditing module broadcasts maintenance operations to all blockchain nodes, ensuring that all nodes are aware of data changes in a timely manner and can conduct audits.

The data synchronization module first constructs a maintenance operation record corresponding to the maintenance operation and sends the record to the blockchain node of the current dispatching center. Subsequently, the record is broadcast to blockchain nodes of other dispatching centers, ensuring that all nodes have the latest maintenance operation records. The data subscription module is responsible for obtaining updated data from the state database of the target blockchain node and synchronizing it to the state database of the blockchain node of the current dispatching center, guaranteeing data consistency and real-time performance.

The system proposed in this patent, by applying blockchain technology to power grid model data management, effectively enhances data security, reliability, and traceability. It manifests as:

• Data Security: Through distributed ledger technology, it ensures data immutability and prevents data from being maliciously attacked or tampered with.

• Data Reliability: Blockchain consensus mechanism ensures data consistency, preventing data inconsistencies across different nodes.

• Traceability: All operation records are recorded on the blockchain, allowing for easy tracing of historical data modifications, increasing data transparency.

This patent innovatively integrates blockchain technology with power grid model data management, providing new technical support for power grid safe operation and intelligent dispatching. In the future, as blockchain technology continues to develop, this patent is expected to be more widely applied in the power industry, contributing to the intelligent transformation of State Grid.

Summary

The "Power Grid Model Data Management System and Method" patent filed by State Grid is a positive exploration of its utilization of blockchain technology to enhance power grid data security, reliability, and traceability. The application of this patent will provide new technical guarantees for power grid safe operation and intelligent dispatching, promoting the digital transformation of the power industry.
