The invention discloses a power distribution network reactive power optimization system and method based on multi-data analysis. The system comprises: a distribution network data acquisition device for acquiring 10kV line outlet node real-time data and transmitting the same to a host computer control system; a dynamic reactive power compensation device for uploading distribution network operating data and reactive power compensation device running status data to the host computer control system by using GPRS. The method, through the EMS and distribution network automation system, get access to the data of each node of a 10kV line, carries on the load flow calculation, obtains the distribution of the voltage, active power and reactive power of each node of the line, and makes the line run in an optimal state through reactive power strategy control, develop reactive power optimization strategy through a genetic algorithm to determine the compensation point, compensation capacity and the like, controls the react
