Big data platform and application implementation in energy industry: combination of oil and gas industry chain and big data: in the process of oil and gas exploration and development, big data analysis can be used to find growth points, and the big data platform can be applied to help refineries improve refining efficiency and help downstream markets explore consumption rules, so as to optimize the inventory and determine high-quality promotion plans. Smart grid: the characteristics of household electricity consumption is monitored through big data real-time monitoring technology to help electric power companies allocate the power supply, and provide customers with appropriate electricity schemes. Through peak load shifting and power limiting, customers can utilize the electricity during the period of low power cost, avoiding the situation of excessive power load during peak hours, and consumers will have more economic choices for energy utilization in the future. Wind power industry: on-line monitoring is implemented to the distributed wind farm fans from parts manufacturing to assembly, and the periodic and instantaneous real-time data acquisition and online analysis are performed to generate alerts, allow maintainers to visualize and manage data, and simplify the deployment of large-scale monitoring systems, so as to form the whole industrial chain management of research - production - supply - marketing - transport - installation - maintenance, and achieve a gorgeous transformation from traditional discrete manufacturing industry to industry integration solution provider.
