The invention discloses a low voltage distribution network reactive compensation system. The low voltage distribution network reactive compensation system comprises a primary station module, a reactive compensation module, a distribution transformation terminal module, an equipment asset management module and a human-computer interaction module, wherein the reactive compensation module and the distribution transformation terminal module are connected through a wireless network, the distribution transformation terminal module transmits integrated and uniformly scheduled data to the primary station module through the wireless network, the equipment asset management module transmits equipment asset information in the low voltage distribution network reactive compensation system to the primary station module, and the human-computer interaction module responds to operation of an operator and sends out a corresponding instruction. The low voltage distribution network reactive compensation system has a good communication function, achieves bidirectional information transmission between the reactive compensation module and the primary station module, enables a user on the primary station module to immediately acquire the equipment asset information at a fault point when a fault occurs, and issues the fault removal instruction through the human-computer interaction module to a department or a person, closest to the fault point.
