Guangdong Power Grid applies for a patent on a distribution protection method based on Q-learning and blockchain: enhancing reliability and efficiency

On January 29, 2025, the State Intellectual Property Office of China (SIPO) revealed that Guangdong Power Grid Co., Ltd. filed a patent application titled "Distribution protection method, device, and storage medium based on Q-learning and blockchain" (publication number CN119362347A), with an application date of October 2024. The core of this patented technology lies in utilizing Q-learning algorithms and blockchain technology to improve the reliability and efficiency of distribution systems' protection, effectively clearing various faults.

The patent abstract details the method's steps: First, a large amount of training data is acquired and processed using the Q-learning algorithm to generate a Q-learning decision tree model. This process adheres to predefined rules to ensure model accuracy and reliability. Subsequently, system component data collected by multiple subordinate agent modules are input into blockchain data blocks. A control master agent module calculates this data, extracting fault information. Based on this information and the Q-learning decision tree model, the master agent module identifies the subordinate agent module requiring a tripping operation. Finally, the master agent module sends a tripping request to the target subordinate agent module, enabling rapid fault clearance.

The innovation lies in cleverly combining Q-learning and blockchain technology. Q-learning, a reinforcement learning algorithm, continuously learns and adjusts, improving the reliability and efficiency of relay agents, reducing misoperations and missed operations. Blockchain technology ensures secure, transparent, and traceable data interaction. Recording all data and operations on the blockchain prevents data tampering and loss, enhancing overall system reliability and security. This combination effectively handles fault processing in complex situations, strengthening distribution system stability and security.

This technology has broad application prospects. With increasingly complex and intelligent power systems, demands on distribution protection technology are rising. Traditional methods struggle to quickly and accurately diagnose and handle complex faults, potentially causing widespread outages and significant economic and social impacts. The Q-learning and blockchain-based method, with its efficient algorithm and secure data interaction mechanism, effectively addresses these issues, improving distribution system stability and reliability, and reducing accident rates and economic losses.

This technology's application will not only improve Guangdong Power Grid's operational efficiency and security but also provide advanced solutions for other power companies. Its promotion will drive the intelligent upgrading of the entire power industry, contributing to a safer, more reliable, and efficient power system. Its efficient fault handling reduces downtime, lowers economic losses, and improves customer satisfaction.

Further analysis shows the patent's success lies in its effective integration and innovation of existing technologies. Q-learning enhances system intelligence, adapting to complex operating environments and fault conditions. Blockchain enhances security, preventing data manipulation and loss, ensuring reliable operation. This successful technology fusion provides a reference for innovation in other fields.
