SAPF for the Inter-harmonics on Grid Network Compensation
International Journal of Grid and Distributed Computing, 2014 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 interharmonics and non-periodic disturbances. This paper analyzed the CPT (conservative power theory) definition of power theory and the application method for SAPF.

Influence of Non-Integer Harmonics and Interference on SAPF
TELKOMNIKA Indonesian Journal of Electrical Engineering, 2014 Inter-harmonics and non-periodic disturbance generated by aging SAPF or other reasons would impact SAPF performance. In this paper, three-level SAPF was used as example: the mathematical model of three-level SAPF under the definition of virtual flux was built. The power theory under the definition of CPT was discussed.
