Active distribution network system has the characteristics of complex structure，high DG permeability，large load fluctuation，strict control requirements. The data information of operation has the characteristics of high volume，high speed，diversity and value. For active distribution network data processing， according to the theory of cloud calculation，using the data mining technology and distributed parallel computing method，establishing an active distribution network security monitoring system model based on PDMiner large data mining platform. The processing of historical data and real time fault data are studied respectively. Research results show that the system by processing of historical data for risk zoning，development planning，operation state evaluation，by processing of fault data for fault analysis and processing，providing the basis for the distribution network security. The result of the system is verified by the simulation example.
