Aiming at the characteristics of large scale, multiple types, small value density, fast changing speed and geographically dispersed, this data can be efficiently, reliably and cheaply stored and quickly accessed and analyzed, which satisfies the demand of intelligent power grid operation, overhaul and benefit management, This paper presents a solution of the intelligent power grid data Cloud warehouse under the low voltage PC cluster of Hadoop, which provides an effective, reliable and inexpensive tool for mining the massive power grid data. This paper analyzes the characteristics of large power grid data, and then combines the characteristics of IEC61970 Standard General information model, based on the Hadoop framework, designs the Power information cloud warehouse to meet the demand of large scale data processing. Finally, the performance of the Cloud warehouse is tested by using the Cloud warehouse in the dispatching system, which proves that the power information cloud Warehouse has the advantages of high efficiency, reliability and cheapness.
