The theoretical study on rural distribution network reactive power optimization and single compensation device was reported in lot of literature, but the study of reactive power optimization intelligent control system for 10 kV lines in the rural power distribution network is still blank. This paper makes reactive power optimization intelligent system come true, which was based on the current status of rural network reactive power compensation, 10 kV distribution lines integrated long-range communications technology and network technology, directly remote monitoring, management and automation in the dispatch room, through the upper and lower digital technology. The system implementation showes that each substation exports power factor always fluctuated between 0.95-0.98, which is essentially a straight line. System implementation explored a new way to achieve intelligent electicity network.
