Using SAPF (shunt active power filter) has been proved as an effective way for harmonic compensation. In practical applications, the performance of SAPF will be impacted by inter-harmonics and non-periodic disturbances. This paper analyzed the CPT (conservative power theory) definition of power theory and the application method for SAPF. Repetitive controller and PI controller were used as a combination way for the harmonic and inter-harmonic compensation. By the EID (equivalent input-disturbance) controller, the performance for non-periodic interference suppression of SAPF can be improved. By simulation with MATLAB, the models of SAPF system, repetitive controller and EID controller were built. Through the computer simulation method, we can verify the designed system performance.
