Because the power grid of coal mine requires that harmonic current needs real-time transient compensation, proposes a control strategy based on SVPWM and designs a topological structure of a parallel hybrid active power filter （PHAPF） for coal mine power grid. Then the control strategy of topological structure is being discussed. The control strategy directly influences the filter performance of active power filter. The active power filter connects with LC series passive power filter via three-phase coupling transformers. This can reduce active filter capacity and fundamental wave. Through theoretical analysis and Matlab simulation, the control strategy of a parallel hybrid active power filter can improve the power quality of power grid for coal mine.
