Abstract: With the advent of the era of big data, data is considered to be an important factor of production. Great importance has been attached to improving the management level of unstructured data by the power grid enterprises. This paper analyzes the current situation of the management of the unstructured data in the power grid enterprises, and proposes to construct the unstructured data management platform based on the big data technology. The platform uses the Hadoop parallel distributed computing architecture and the hybrid storage architecture. This paper describes the technical architecture and application architecture, and discusses the advanced nature of the technical architecture in the power grid enterprise.
