A new topology of high order resonance hybrid APF(HORHAPF) is proposed, which can be adopted in high voltage system. The corresponding electric models were constructed and controlling strategies was presented. The harmonic suppressing function was used to analyze the harmonic suppressing performance of HORHAPF with the changing parameters based on the controlling strategies in MATLAB. The reactive power compensating performance of the system was also gotten. The simulating results prove the validity of HORHAPF. The reactive power and harmonics are suppressed well.
