Big Data Platform for Smart Substation Monitoring System

Due to new energy resources, including wind energy storage has been well into the grid, power dispatch and distribution of the operation process involves large-scale, multi type, highly complex data, which contains real-time data, planned data, early warning and monitoring data, environmental data. At present, the application of large data mainly focuses on the single analysis of structured and semi-structured data. And in-depth study of the analysis has not been concerned about the transformation of power grid data into knowledge, is the inevitable trend of the development of smart grid. In this paper, the data source, data characteristics and application trends are analyzed. According to the new requirements of the smart grid, the potential applications of large data technology are studied in the field of smart grid. Finally, to meeting requirement of the power dispatching & distribution data analysis, smart substation monitoring data system architecture was designed which is an integrated software/hardware, storage, computation, communication trinity. And it is proved that the system structure of smart substation monitoring data system has strong support, service and security.
