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. Repetitive controller and PI controller were used as a com...

Variable speed drives (VSDs) use power electronic components as controlled switches which distort the sinusoidal current and voltage waveforms of AC grid due to harmonic injection at the point of common coupling (PCC). These harmonics and distortions are propagated through the power network and affect all other connected loads. So, the shunt active power filter (SAPF) is one of the proposed too...

This work deals with the design, analysis and simulation of shunt active power filter SAPF, which compensate harmonic currents, and reactive power under balanced supply network.

The SAPF is connected in parallel with a nonlinear load which has caused current harmonics in industri...

Current harmonics is one of the most significant power quality issues which has attracted tremendous research interest. Shunt active power filter (SAPF) is the best solution to minimize harmonic contamination, but its effectiveness is strictly dependent on how quickly and accurately its control algorithms can perform.

Shunt active power filter is commonly used to eliminate current harmonics generated in the source side due to presence of non-linear loads. This scheme consists of three phase three level diode clamped multilevel inverter and a DC capacitor that act as a shunt active power filter to mitigate the supply current harmonics and inject the required reactive power to non-linear loads.
