Abstract Given the complex situations of the grid with inter-harmonics, three-level model of shunt active power filter (SAPF) was built. For the harmonics accurate detection, the conservative power theory (CPT) principle was used to detect the fundamental component of the grid. The inter-harmonics, parameter fluctuation of APF and the deadband effect were considered as the non-periodic disturbance to the controller. To eliminate the non-periodic disturbance impact on the controller and to improve the control system performance, equivalent input-disturbance (EID) was used based on the traditional repetitive controller. With Matlab and three-level test platform, the SAPF control system was built. The performance of detection and compensation for harmonic and inter-harmonic was verified by the simulation and experiment.

Key words： Inter-harmonic conservative power theory (CPT) equivalent input-disturbance(EID) repetive control
