Abstract: Under the strategic background of energy transformation and "dual carbon" goal in the new era, China is vigorously carrying out new energy construction. In order to realize the information and digital management of new energy, the intelligent operation and maintenance of new energy based on "big data" and "Internet +" has become the focus of the industry. The data collection and storage platform is the most basic and important part of the new energy intelligent operation and maintenance system. This paper introduces the construction process of new energy intelligent operation and maintenance data acquisition and storage platform from two aspects of data access and data storage, and supports the intelligent operation and maintenance management of the whole life cycle of new energy intelligent operation and maintenance.
