Development and application of three-dimensional visualization system for substation construction control based on “BIM+ Smart site” technology

Since 2020, the CPC Central Committee and the State Council have made important plans to accelerate the construction of new infrastructure such as 5G network, big data center, artificial intelligence and industrial Internet. The State-owned Assets Supervision and Administration Commission (SASAC) issued the Notice on Accelerating the Digital Transformation of State-owned Enterprises, which points out the direction for the digital transformation of state-owned enterprises. Relying on the State Grid Tianjin Electric Power Company's Tencent No.1110kV substation as a pilot project, the project team deepened the three-dimensional design results, explored a new digital construction management mode, and developed a three-dimensional visualization system for construction control. This paper makes a detailed study on the construction ideas and system framework of the three-dimensional visualization system for power transmission and transformation engineering construction control, completes the system research and development, and applies it in the whole construction process of Tencent 110kV substation in Tianjin. Through the integration of BIM technology and data collected by the IOT sensing device, the automatic loading of professional data such as progress, quality and safety in the three-dimensional scene is realized, so as to realize full perception of operation status, full sharing of construction and management data and full coverage of process control. According to the demand of partial and sub-item settlement, with the help of the thinking mode of block chain technology, accurate settlement of project quantity and dynamic visual control of project cost are realized. And the digital transformation of power grid construction is accelerated.
