Abstract: Under the background of emission peak and carbon neutrality goals in China,and the vigorous development of new power systems with new energy as the main energy,the construction of PV power stations ushered in new opportunities. However,many problems existing in the traditional construction and management methods of PV power stations seriously restricted the large-scale construction and promotion of PV power stations. This paper takes the construction of a PV base project in the southern part of Ganzi Tibetan Autonomous Prefecture,Sichuan Province as an example. Based on modern information technologies such as geographic information systems（GIS）,big data,and cloud computing,combined with the construction characteristics and construction progress management methods of PV power stations,a intelligent construction progress management system suitable for the construction of PV power stations in ultra-high altitude areas has been developed. A new construction progress management method driven by business and centered on data has been created,solved the problems faced in the process of the traditional construction schedule management,broke the data barriers of all parties involved in the construction,achieved data collaborative sharing,intelligent analysis,efficient retrieval,and GIS visualization,reduced the risk of construction process management in project construction,comprehensively improved the efficiency of construction process management,and saved project construction costs. The construction progress management system can provide strong support for managers’ precise decisionmaking,and lay the foundation for the promotion of digital construction of PV power stations.
