Considering that active power filter can not compensate reactive power dynamically, and the problem of the phase shift of passive filter compensation, this paper proposes a unity compensation control system combining parallel hybrid power filter (SHPF-TCR) with thyristor controlled reactor. The SHPF is the combination of a small-rating active power filter (APF) and a fifth-harmonic-tuned LC passive filter, which can compensate system harmonic. The tuned passive filter and the TCR form a shunt passive filter (SPF) to compensate reactive power. Decoupling control for current tracking and voltage regulation, the introduction of PI controller are used to eliminate the steady-state error of the system. The SHPF-TCR control effectively reduces APF capacity, eliminates system resonance, has good stability and behavior of fast dynamic response. Experimental and simulation results show that the proposed structure and control method can effective achieve harmonic depression and reactive power compensation.
