A Review of Control Technique Applied in Shunt Active Power Filter (SAPF) [PDF]

Engineering and Technology Journal, 2022
In recent years, electronic transformers and electronic devices (nonlinear loads) have increased. These loads are the source of harmonics (non-sinusoidal and distorted waves) and the interactive force that affects the performance of the power system ...

Parallel Association of Shunt Active Power Filters [PDF]

2007 IEEE International Symposium on Industrial Electronics, 2007
This paper describes different types of parallel association of Shunt Active Power Filters, presents computer simulation models developed in PSCAD®/EMTDC?, and shows simulated results for each case. The control system used in the active filters is based on the Instantaneous Reactive Power Theory (p-q Theory). The active filters use periodic sampling as

Three-Phase Shunt Active Power Filter [PDF]

American Journal of Applied Sciences, 2008
Active power filters have been widely used for harmonic elimination. The performance of a conventional three-phase shunt Active Power Filter (APF) using Synchronous Detection Method (SDM) has been compared with Nonlinear Autoregressive-Moving Average (NARMA)-L2 based APF. The novelty of this study lies in the application of NARMA-L2 control to generate
