Munazama Ali, Deeraj Joshi . Analysis of Shunt Active Filter with ANN based Controller. International Journal of Computer Applications. 182, 32 ( Dec 2018), 27-32. DOI=10.5120/ijca2018918241
Due to enormously increasing of power electronic devices such as arc furnaces,rectifiers,variable frequency drives introduces harmonics in the power system this leads to very low power factor in the power system. Power filters are widely used in modern electrical distribution systems to eliminate harmonic associated with it. This paper represents the effective solution of shunt active power filter to eliminate the harmonics associated with the utility power supply. The ShAPF requires accurate control algorithm that provides robust performance under source and load unbalances thus, compensation of harmonics depends largely on the algorithm adopted. In this work both PI and ANNcontroller are used in three-phase shunt active power filter to compensate harmonics and reactive power by nonlinear load to improve power quality is implemented for three-phase three wire systems. ANN-based technique is implemented in shunt active power filters to produce controlled pulses required for IGBT inverter. Simulation result obtained shows that performance of ANN controller found is better than PI controller.
