Blockchain-Based Partial Discharge Detection for GIS Equipment: A Detailed Look at the Changjiang Power and Grub Technology Patent Application

On November 30, 2024, the State Intellectual Property Office of China revealed that China Three Gorges Corporation (Changjiang Power) and Shanghai Grub Technology Co., Ltd. jointly filed a patent application titled "A Method and Apparatus for Processing Partial Discharge Detection Data of GIS Equipment Based on Blockchain," with publication number CN119044687A and an application date of August 2024. This patent application marks a significant step forward in the application of blockchain technology in the field of power equipment maintenance, focusing on improving the efficiency and reliability of partial discharge detection in GIS (Gas Insulated Switchgear) equipment.

The patent abstract details the technical solution of the method and apparatus. The method falls under the field of partial discharge detection, and its core idea is to integrate blockchain technology with GIS equipment partial discharge detection to build a secure, transparent, and efficient data processing system. The process can be summarized in several steps: First, the system receives registration requests from at least one partial discharge detection unit. These units can be understood as various sensors or devices participating in the detection process. The system adds these units as blockchain nodes to a pre-built blockchain network based on the registration requests.

Next, the system receives a pre-written smart contract for partial discharge detection. The smart contract, a crucial component of blockchain technology, defines the rules and procedures for data processing, ensuring automation and trustworthiness. Once the smart contract is deployed to the blockchain network, the system receives a trigger request for the smart contract. This trigger can originate from various sources, such as a pre-set detection time or an abnormal data alert. Upon receiving the trigger request, the system retrieves the corresponding list of partial discharge detection units based on the smart contract's logic and then obtains the detection data collected by these units.

Finally, the system receives the partial discharge detection results corresponding to this data. These results are processed and verified by the smart contract to ensure their integrity and reliability. Using blockchain's distributed ledger technology, all participating nodes can verify the authenticity of the data, preventing data tampering and loss. The entire process is highly automated, requiring no manual intervention and significantly improving detection efficiency.

The innovation of this patent application lies in its use of blockchain technology to achieve automatic verification of the partial discharge detection smart contract trigger and automatic acquisition of partial discharge detection data. Traditional GIS equipment partial discharge detection methods often rely on manual operation and centralized data storage, resulting in data security risks, low data transmission efficiency, and difficulties in ensuring data credibility. The blockchain-based solution proposed in this patent application effectively addresses these issues.

Firstly, the distributed ledger characteristic of blockchain technology ensures data security and integrity. All data is recorded on the distributed ledger, preventing data loss due to single points of failure. Secondly, the automated execution of smart contracts improves detection efficiency, reduces manual intervention, and avoids human error. Thirdly, the immutability of blockchain technology ensures data credibility, providing a reliable data basis for subsequent model training and analysis. Finally, the construction of the blockchain network enables data sharing and collaborative work, facilitating multi-party participation in partial discharge detection.

By deploying a partial discharge detection smart contract within the blockchain network, the patent application cleverly implements an automated process. The system can automatically verify the identity of the smart contract trigger and automatically obtain detection data from partial discharge detection units, enabling rapid training of partial discharge detection models and ultimately improving detection efficiency and accuracy. This has significant practical implications for ensuring the safe operation of power equipment and reducing maintenance costs. The application of this patented technology is expected to effectively improve the operational reliability of GIS equipment, reduce failures and accidents caused by partial discharge, and provide important safeguards for the stable operation of the power system.

The patent application's technical solution offers significant advantages, improving not only the efficiency and accuracy of GIS equipment partial discharge detection but also the security and reliability of the data. Its application prospects are vast, and it is expected to be widely promoted and applied in the power industry in the future, enhancing the overall safety and stability of the power system.
