State Grid Jiangsu Electric Power Nantong Branch Applies for a Patent for "Data Traceability Method Based on Digital Twin and Blockchain"

Information from the State Intellectual Property Office shows that State Grid Jiangsu Electric Power Co., Ltd. Nantong Power Supply Branch filed a patent application in September 2024 for a "Data Traceability Method Based on Digital Twin and Blockchain", with a publication number of CN118797367A. This patent belongs to the field of information processing and management systems, aiming to address the technical challenges of low accuracy in existing grid monitoring data and low efficiency in fault tracing, leading to increased difficulties in grid maintenance and management.

The patent abstract shows that the method mainly includes the following steps:

1. Sensing and Acquiring Grid Information: Collect monitoring information from multiple locations within the grid and upload it to the twin blockchain through grid nodes.

2. Matching Degree Analysis: Conduct matching degree analysis on the information uploaded to the twin blockchain.

3. Constructing Twin Models: Utilizing digital twin technology, construct multiple twin grid models based on different monitoring information.

4. Stability Analysis: Perform local grid stability analysis and overall grid stability analysis on multiple twin model blocks, mark the results, and add them to the twin data blockchain.

5. Fault Tracing: When a fault occurs, obtain the fault location, local fault scale, and overall fault scale. Trace the fault within the twin data blockchain to obtain a set of twin grid models related to the fault, which will be used as the traceability result for grid fault troubleshooting.

This patent technology effectively improves the accuracy of grid monitoring data and the efficiency of fault tracing by integrating digital twin technology with blockchain technology. Specifically, this method has the following advantages:

• Improved Data Accuracy: By storing and analyzing grid monitoring data within the twin data blockchain, it effectively prevents data tampering and loss, ensuring the authenticity and reliability of the data.

• Enhanced Tracing Efficiency: Leveraging the distributed ledger and tamper-proof characteristics of blockchain technology, it can quickly locate the fault area and trace the cause of the fault, improving the efficiency of fault troubleshooting.

• Increased Grid Stability: By conducting stability analysis on multiple twin model blocks, potential risks can be identified in time, and preventive measures can be taken to enhance the stability and security of the grid.

The application of this patent technology will effectively improve the level of modern management of the grid and provide strong support for the safe and stable operation of the power system. In the future, as digital twin technology continues to develop and application scenarios expand, the data traceability method based on blockchain and digital twin will have broader application prospects.
