The utility model provides a novel modular mining reactive power compensator control system based on FPGA. The system comprises a main control board, an optical fiber board, a VME bus case and a bottom unit. The main control board and the optical fiber board are inserted into a back board of the VME bus case. The main control board and the optical fiber board are connected through a VME bus. The optical fiber board and the bottom unit are connected through an optical fiber. According to the utility model, extension can be carried out according actual needs; the defects that the extendibility is poor and high speed and high precision requirements of complex operation are difficultly met in the prior art are overcome; and the control performance can meet the requirements of a mining reactive power compensator.
