Abstract：According to the power supply quality problems caused by the low power factor and high harmonic content of power distribution network for the beam type water pump applied to the coalbed methane mining area,a study on three level static VAR compensation technol-ogy was conducted.With an analysis on the causes of VAR and harmonics occurred in the power distribution network,based on diode-clamped three-level inverter,a topological structure of the static VAR generator and the voltage and current double-loop control tactics were designed and the three-level space vector pulse width modulation (SVPWM)tactics were simplified.Meanwhile,test prototype was built and applied to a production site of Lanyan Coal Bed Methane Company,Shanxi Jincheng Anthracite Mining Group.The production practice results showed that three level static VAR generator designed could effectively improve the power factor of power distribution net-work for beam type water pump applied to the coalbed methane mining and could effectively reduce the current harmonic content of the power distribution network,which could improve the power supply quality of the power distribution network.
