The invention discloses a power 
big data system based on an intelligent 
power grid, and the 
system comprises a 
big data analysis platform, a power 
plant terminal, a 
transformer station terminal, and an intelligent 
community terminal, wherein the power 
plant terminal, the 
transformer station terminal and the intelligent 
community terminal are respectively connected with the 
big data analysis platform. The power 
plant terminal is used for collecting the power generation information in the power plant, and controlling an executing mechanism of power generation equipment. The 
transformer station terminal is used for collecting the 
power transmission and transformation information and controlling an executing mechanism of 
power transmission and transformation equipment. The intelligent 
community terminal is used for collecting the information of a smart home and controlling an executing mechanism of the smart home. The big 
data analysis platform is used for the controlling of instruction input, the loading and extracting of related data, 
data analysis and mining, the graphical displaying of analysis results and the generation of an analysis report. The 
system is objective and true in obtained big data, is high in accuracy, can determine a plan of optimal operation and load control, can achieve the reasonable formulation of marketing strategies of a power enterprise, can update regional 
energy development plans, and obtains 
external data of the power enterprise so as to obtain commercial values.
