[Introduction] At present, investors in the power market have an increasing demand for digitization and intelligence of thermal power generation projects. Especially, overseas projects have put forward new requirements for the integrity and timeliness of digital design. Therefore, how to integrate the existing platform and data to form an effective implementation plan for digital collaborative design of thermal power plants has become an important issue faced by power design enterprises. [Method] This paper took Unique project in Bangladesh as the application object, and put forward a complete solution through case analysis, demand analysis, secondary development, standard digitization and other means. The scheme took the digital positive design as the overall requirement and constructed a set of basic database suitable for international engineering project. Through deep secondary development and integration, the whole process from system design, layout design to civil engineering design and drawing output was opened up. The basic platform such as the integrated design platform of process and civil engineering had been improved. The digital positive design of the project was realized. [Result] Through the in-depth application, the barrier of digital design information isolated island is broken by technical means, and the positive and full connection of data is realized, which improves the cooperation and drawing output efficiency of the upstream and downstream. [Conclusion] The practical results of the project prove that the scheme is scientific and efficient, which provides a reference solution for the digital positive design of thermal power plants.
