ANN Based Control Algorithm for Harmonic Elimination and Power Factor Correction Using Shunt Active Filter

摘要

The growth in the use of non-linear loads has caused power quality problems like high current harmonics and low power factor. Several control algorithms, which are usually used to resolve harmonic problems and their limitations are discussed in this study. Recently ANN based adaptive shunt active filter gains attention. In this study a new training algorithm for ANN based shunt active filter is proposed. A modification in conventional self-charging technique is also is also proposed to regulate the dc capacitor voltage at the desired level without the use of PI controller. The design concept of the shunt active filter using the proposed ANN based control algorithm is verified through simulation and the result proved the effectiveness of the proposed algorithm.
