Storage and Query of Condition Monitoring Data in Smart Grid Based on Hadoop

With the development of smart grid, the amount of condition monitoring data would be huge and far beyond the scope of traditional condition monitoring system. Condition monitoring data has the features of the wide area, panoramic, mass, accurate and reliable, and the methods of conventional data storage and management are obviously difficult to adapt the needs. This paper proposes a processing method of condition monitoring data in smart grid based on Hadoop, in connection with the characteristics of condition monitoring in smart grid and combined with Hadoop cloud computing. A condition monitoring platform based on Hadoop is built and improved, to implement reliable storage and fast parallel processing of massive data.
