Design and Application of Three-Dimensional Digitization and Intelligent Operation System for Converter Station

Abstract

[Introduction] In response to the pain points of the operation and maintenance of the converter station, the design methods of the three-dimensional digitization and intelligent operation system are proposed, and the actual application is performed in the project. [Method] Firstly, the overall architecture, technical architecture, data architecture and functional modules of the system were explained, and by using digital twin technology, operation and maintenance services such as intelligent inspection, intelligent operation, and intelligent security were realized. Then the key technologies of the system were studied, including converter station modeling and refined processing, model and data fusion technology, and panoramic visualization technology, which realized the centralized operation and control of the whole site in the three-dimensional scenarios. Finally, the system was deployed at the project site, which greatly improved operation and maintenance efficiency and experience. [Result] The application of the system shows that the manual replacement rate of daily intelligent inspection projects reaches more than 80%, the on-site operation time can be reduced by 60%, and the operating risk management and control capabilities and safety levels are improved, saving 65% of working hours. [Conclusion] The three-dimensional digitalization and intelligent operation system of the converter station can effectively improve the accurate management of the equipment, and realize the cost reduction and benefit increasing of the operation and maintenance business.
