【 摘 要 】

The new generation of power grid dispatching control system draws on the cloud computing concept for reference, adopts a new overall architecture of "physically distributed and logically uniform". It applies a large number of new technologies, enhances the relevance of various applications of the new system, and rapidly expands the application data scale, making the operation and maintenance of the power grid dispatching control system increasingly complicated. At present, the State Grid Corporation of China is carrying out research on operation and maintenance technology of dispatching control system based on historical big data mining. In the face of the collection and aggregation of a large number of operation history data and operation indexes of dispatching control system, the traditional relational database is facing great challenges. This paper discusses the data storage technology supporting big data, and through analyzing the characteristics of big data storage and the existing typical databases of NO SQL and NewSQL, puts forward a data storage technology that can meet the needs of mass operation and maintenance data storage and high-speed access of the new generation of power grid dispatching control system.
