Research and Application of Key Technologies for Standardization of Distribution Automation Terminals

Recently, the key technology research and application project on the standardization of distribution automation terminals, led by State Grid Corporation of China through its subsidiary, Nanrui Beijing Kedong Co., Ltd., has successfully passed the appraisal of scientific and technological achievements organized by the China Institute of Electrical Engineering. The appraisal committee expressed a unanimous opinion that the project features an innovative design concept and a scientifically sound technical approach. The overall research outcomes have reached internationally advanced levels and are leading domestically, offering significant economic and social benefits. The committee strongly recommended further promotion and practical application of these results.

This key technology research and application project focuses on various aspects such as the technical specifications for distribution automation terminals, software and hardware development platforms, secondary security protection schemes, and operation and maintenance management tools. It proposes comprehensive standards covering technologies, types, testing, installation, and operational maintenance of distribution automation terminal series. The project also aims to develop standardized distribution automation terminals with expandable and interchangeable modules, enabling plug-and-play functionality. Additionally, it involves the implementation of hardware encryption based on security authentication protocols, integrating the unit with a security master module. This ensures the standardization of status monitoring, function configuration, and file management for distribution automation terminals.

The developed distribution automation terminals have been deployed in trial operations across the distribution networks of five provinces: Beijing, Tianjin, Fujian, Liaoning, and Qinghai. These results have actively contributed to promoting the standardization of distribution automation and enhancing its practical application level. The project not only improves system efficiency but also lays a solid foundation for future smart grid development. As more regions adopt these standardized solutions, the potential for broader implementation and long-term benefits continues to grow. With ongoing improvements and real-world feedback, the project is expected to play a vital role in shaping the next generation of smart and reliable power distribution systems.
